I spent a fair amount of time working on a design for my keyboards (work and home) that I planned to have made (probably through WASD, though I was checking out some of the other providers to see what the price jump for PBT would be; I don't believe WASD has PBT as an offering, at leat not yet.)
Unfortunately (or fortunately I suppose), I realized that in practice, enough other people use my computer at home who aren't touch typists that this would be thoroughly impractical. I may throw out this entire design/theme and do a Tron inspired one instead, but I wanted to share what I came up with. Note that these keycaps were destined for a tenkeyless, so the numpad is all just spares. Anyway, enjoy.
