Caustic (optics)
Caustics made by the surface of water.
In optics, a caustic is the envelope of light rays reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface. The caustic is a curve or surface to which each of the light rays is tangent, defining a boundary of an envelope of rays as a curve of concentrated light.
Hiding Images in Plain Sight
An Article by Matt FerraroI recently made a physical object that defies all intuition. It's a square of acrylic, smooth on both sides, totally transparent. A tiny window.
But it has the magic property that if you shine a flashlight on it, it forms an image.

New milling techniques applied to glass and plexiglass panels could be used to “create windows that are also cryptic projectors, summoning ghostly images from sunlight.”
[Pauly and Bompas] hope that the technique will be used in architectural design, to create windows that mould sunlight and throw images or patterns onto walls or floors,” which, if timed, milled, and manipulated just right, could produce a slowly animated sequence of images being projected by an otherwise empty window during different times of day.
Architectural Caustics
A Research PaperTo control the shape of a caustic pattern generated by a specular or refractive surface, we need to solve the inverse problem: how can we change the surface geometry, such that incident light is redirected to produce a desired caustic image?
Skeleton, Organs, Circulation, Sinew, Skin
I’m concerned with how I witness the work of user experience practitioners getting treated: like it’s just a set of motions toward a product’s all-important implementation, and one that we try to compress, due to its ostensible superfluity. Once the implementation is finished, the UX work appears to usually get discarded.
Tracing the answer back
I submit that the materials that form the precursors to a product’s implementation have considerable value on their own.
My vision is that I will be able to ask a question as mundane as one about the wording of a single button, and trace the answer all the way back to the overarching business strategy to see that it makes sense.
The UX coral reef
It isn’t a site, or a service, or even an identifiable product at all, but rather a system for creating a skin around and connective tissue between things like:
Demographic studies
Contextual inquiries
Stakeholder and user interviews
Surveys
The business ecosystem
Personas
Scenarios
Sketches, storyboards, wireframes
Mockups, models and prototypes
Email and IM conversations
Meeting notes
Content inventories and audits
Concept schemes, taxonomies, thesauri
A UI style guide
A branding and visual identity guide
A voice and tone guide
A code style guide
...etcThe individual elements of such a corpus represent the work of half a dozen specialist sub-disciplines, and are useful for realizing a product’s implementation. But if you hook them all up together, they merge to become a strategic artifact that transcends products and operates as a critical control surface for the business. This is because what such an artifact represents is a coral reef of deeply-considered and hard-fought decisions, and a story of the process that yielded them.
