Has anyone already done or thought of doing a set of keypad that have bumps on them like the f and j keys, but with different patterns so that you can know how to orient yourself when gaming without looking at the keyboard? For example, the up, down, left, and right keys might just have arrows, but your primary weapon/spell could be a square, secondary a circle, etc. I can just see this being useful either coming out of chat or in mmorpgs where a lot of different keys/macros might be used.
