Type Type Revolution

I just got the most awesome idea in a while!

Combine Dance Dance Revolution with learning to type.
"..uhh what?" I hear you say..

You probably know that in DDR (or StepMania for PC) you get those arrows pointing which key to push/step/whatever.

Replace those arrows... with letters and you get Type Type Revolution!


Now that would be an intresting game. It might be confusing though with all the letters instead of the arrows, but I think it could be done and if it had lots and lots of songs available, like StepMania has at BemaniStyle, it would probably be a very intresting way of learning to type faster.
