Models and iterations Every month or so, Manock and Oyama would present a new iteration based on Jobs's previous criticisms. The latest plaster model would be dramatically unveiled, and all the previous attempts would be lined up next to it. That not only helped them gauge the design's evolution, but it prevented Jobs from insisting that one of his suggestions had been ignored. Walter Isaacson, Steve Jobs iterationprototypes
The fastest way to learn something is to do something An Article by David R. MacIver notebook.drmaciver.com Suppose you have a problem to solve. What do you do? Well, you sit down and think real hard, and after extensive and careful planning you try the well thought out and rigorous solution that you have thought up. Right? No, wrong! Bad. The correct thing to do when you have a problem is: Think for a short amount of time. Make sure it is safe to try things. Try something you think will work. Observe the result. If you succeeded, yay you solved the problem! If it didn't work, think about what that means for the nature of the problem and try again. The Feynman Algorithm problemsprototypesfeedback
Game feel An Article by Dave Rupert daverupert.com How do you make a game that’s fun? ...You have to focus on gameplay. In order for the final product to be fun and exciting, the core game play needs to be fun and exciting. The creator of Mario calls this 手応え (tegotae), which is often translated as “game feel”. To find this game feel, you need to build small prototypes around a single idea, play test them, and then follow the fun. Nintendo does this, indie game devs do this; this is the not-so-secret of the gaming industry. Follow the funFollow the brush prototypesmakinggames
The Fidelity Curve An Article by Ryan Singer m.signalvnoise.com How do we choose which level of fidelity is appropriate for a project? I think about it like this: The purpose of making sketches and mockups before coding is to gain confidence in what we plan to do. I’m trying to remove risk from the decision to build something by somehow “previewing” it in a cheaper form. There’s a trade-off here. The higher the fidelity of the mockup, the more confidence it gives me. But the longer it takes to create that mockup, the more time I’ve wasted on an intermediate step before building the real thing. I like to look at that trade-off economically. Each method reduces risk by letting me preview the outcome at lower fidelity, at the cost of time spent on it. The cost/benefit of each type of mockup is going to vary depending on the fidelity of the simulation and the work involved in building the real thing.

Levels of Scale Scale refers to how we perceive the size of an element or space relative to other forms around it. All things – a tea cup, a building, language, entire eco-systems – consist of smaller components. It is the relationship of the smaller elements which determines the character and degree of life of the whole. Objects which contain a high degree of life tend to contain a beautiful range of scales within, which exist at a series of well-marked intervals and have clearly recognizable jumps between them. To have good levels of scale, it is extremely important that the jumps between different scales of centers not be too great or too small. The scale of resolution determines what is seen
Strong Centers The idea of a center is at the heart of all that creates life within an object. But rather than the traditional view of an isolated geometry in space, a true center is defined not only by its internal cohesion, but by its relation to context. A strong center can only occur when other centers are intensifying it. Like levels of scale, the concept of strong centers is recursive. In something which is alive, a strong center is made of many other strong centers, at different levels, which in turn make us aware of the whole they compose.
Boundaries The articulation of a form depends to a great degree on how its surfaces are defined and meet at edges. The effect of a strong boundary is twofold: First, it focuses attention on the center, further intensifying it; and second, the boundary unites the center which it surrounds with what is beyond. For the boundary to accomplish both of these tasks – to separate and to unite – it must have a degree of presence as strong as the center which it bounds.
Alternating Repetition The principle of repetition orders recurring elements in a composition according to their proximity to one another, and by the visual characteristics they share. Elements need not be perfectly identical to be grouped in a repetitive fashion; they must merely share a common trait of size, shape, or detail characteristics allowing each element to be individually unique, yet belong to the same family. When the repetition within a group of elements occurs parallel on a number of different levels, an alternating rhythm of centers forms, one series of centers intensifying the other.
Positive Space Positive space refers to shaped space. Where an element occurs in space, the element not only exists with its own shape, but it also acts to define the shape of the space around it. For something to be whole, both the element itself and the space around it must engage one another, each intensifying the other. When this occurs, every single part of space has positive shape as a center – there are no amorphous, meaningless leftovers. Every shape should be a strong center in itself, which is in turn made up of other, smaller centers.
Good Shape Shape is the principal identifying characteristic of form, resulting from the specific configuration of a form’s surfaces and edges. Good shape happens when the surfaces and edges of a form have strong centers in every part of themselves. A good shape, even if complex, can usually be broken down easily into more simple shapes. A good shape tends to contain a high degree of internal symmetries, an overall bilateral symmetry, and a well-marked center. The good shape also creates positive space around it, is very strongly distinct from what surrounds it, and has a feeling of being closed and complete.
Local Symmetries Symmetry, or the balanced distribution of equivalent forms or spaces about a common line or point, can organize elements in architecture in two ways: an entire organization can be made symmetrical, or a symmetrical condition can occur in only a portion of the building or object, at any scale. The latter case is what we refer to as local symmetry. Overall symmetry in an object tends to look mechanical and lifeless, usually due to the fact that local symmetries are absent within the overall form. However, when there are local symmetries, centers tend to form and strengthen the whole.
Deep Interlock Forms which have a high degree of life tend to contain some type of interlock – a “hooking into” their surroundings – or an ambiguity between element and context, either case creating a zone belonging to both the form and to its surroundings, making it difficult to disentangle the two. The interlock, or ambiguity, strengthens the centers on either side, which are intensified by the new center formed between the two.

Contrast Works of art which have great life often have intense contrast within: rough/smooth, solid/void, loud/silent, empty/full. It is the difference between opposites which gives birth to something. Contrast is what often gives other principles their degree of life – the intensity of the boundary, the markedness of the alternating repetition. Contrast strengthens centers by making each a deeper entity of itself, and thereby giving deeper meaning to both. It is, at its simplest, what allows us to differentiate. But meaningless contrast remains meaningless. It is only when centers are actively, mutually, and meaningfully composed that it acts to deepen the whole. contrast
Graded Variation Gradients must arise simply because in the natural world, things vary in size, spacing, intensity, and character. All living things tend to have a certain softness. One quality changes slowly, not suddenly, across space to become another. In something which has life, throughout the whole there are graded fields of variation, often moving from the center to the boundary or vice-versa. We are able to read the character of a larger center often because of the gradation of smaller centers across the larger form.
Roughness Roughness is the odd shape, the quick brush stroke, the irregular column size or spacing, the change in pattern at the corner – it is adjusting to conditions as they present themselves with meaning, but without ego or contrived deliberation. Though it may look superficially flawed, especially with human perception accustomed to mass-produced regularity and perfection as a goal, an object with roughness is often more precise because it comes about from paying attention to what matters most, and letting go of what matters less. flawswabi-sabi
Echoes When echoes are present within a design, all the various smaller elements and centers, from which the larger centers are made, have a certain sameness of character. There are deep internal similarities, or echoes of one another, which tie all the elements and centers together at various scales to form a cohesive unity of being.
The Void Objects or elements which have the greatest depth, which actively draw the senses in, have at their heart an area of deep calm and stillness – a void bounded by and contrasted with an area of intense centers around it. When an element becomes all detail, its own constant buzz tends to dilute its overall strength. Like a musical wall of sound, it pushes against our perception to produce a flat field-like state. Conversely, it is the pause which allows us to interlock with a piece of music and feel its depth. The presence of void, at many scales, provides a contrasting calm to alleviate the buzz and strengthen the center. zen
Inner Calm Living things tend to have a special simplicity, an economy developed over time in which all things unnecessary, or not supporting the whole, are removed. This does not preclude ornament, as even in nature ornament has its very necessary place. What simplicity does is cut away the meaningless attachments to an element, the things which often distract and confuse its true nature. When this is done, an object is in a state of inner calm.
Not-Separateness Not-separateness is the degree of connectedness an element has with all that is around it. A thing which has this quality feels completely at peace, because it is so deeply interconnected with its world. There is no abruptness, no sharpness, but often an incomplete edge which softens the hard boundary. The element is drawn into its setting, and the element draws its setting into itself. Not-separateness is a profound connection occurring at many scales between a center and the other centers which surround it, so that they melt into one another and become inseparable.
