Recognizing Constraints An Article by Jeremy Wagner css-tricks.com Super Nintendo games were the flavor of the decade when I was younger, and there’s no better example of building incredible things within comparably meager constraints. Developers on SNES titles were limited to, among other things: 16-bit color. 8 channel stereo output. Cartridges with storage capacities measured in megabits, not megabytes. Limited 3D rendering capabilities on select titles which embedded a special chip in the cartridge. Despite these constraints, game developers cranked out incredible and memorable titles that will endure beyond our lifetimes. Yet, the constraints SNES developers faced were static. You had a single platform with a single set of capabilities. If you could stay within those capabilities and maximize their potential, your game could be played—and adored—by anyone with an SNES console. PC games, on the other hand, had to be developed within a more flexible set of constraints. I remember one of my first PC games had its range of system requirements displayed on the side of the box: Have at least a 386 processor—but Pentium is preferred. Ad Lib or PC speaker supported—but Sound Blaster is best. Show up to the party with at least 4 megabytes of RAM—but more is better. constraints
Guided by image In our minds, the drawings we had originally made for the columns and capitals were no more than first approximations of the final shapes. We assumed that we would work out the real shapes during construction, and left the inaccurate approximations on our drawings, just for the sake of the building permit. Fujita, used to working with architects in System B, assumed that whatever was on our drawings must be what we wanted, and must be implemented as drawn. Anybody who was making those column capitals, if they had seen this "double" capital, and had been free to make something harmonious, would have done it differently. But Fujita's people, in System B, did not know how to be guided by reality. They were guided by "image". So Fujita, in this situation, was not free to respond in a natural way to what they saw. They were trapped by the image-making process they were used to. But because of this, they doomed their own carpenters to a pretentious kind of slavery, producing whatever silly images they were told to do, without being able to ask themselves whether they were beautiful, and unable to use their own sense of reality to make them better.
