Layout could be as simple or as complicated as you wanted it to be. 1% to 2000%, ISO, ANSI or neither, tertiary, quaternary or duodenary legends, joysticks, trackballs, whatever you want. Of course, whatever you pick has to fit on your desk!
Personally, mine would be extremely huge. Because more bigger is more better, right? xD

ISO with big-ass enter key and 2u backspace, fun cluster on the left, one winkey on the right, screenshot key on the left, 12 PF keys on top of the F keys, full nav cluster and a calculator on top of and using the numpad, which includes an equals key. Bam!
What would yours be? GOGOGOGO
