You can get giant piano keyboards that you step on, so how about a giant computer keyboard? "I wrote 5 miles of code before lunch!" :-)You can get/make MIDI organ pedal-boards (a friend of mine has two). From there it's just one small step...
Is that a two-step? a box-step? Count it off...slow, slow, quick, quick. I think I just coded up Conway's Game of Life...
