Nintendo controllers as MIDI controllers

Look at what this guy has done. He hacked 3 different kinds of controllers originally meant for Nintendo games usage (I'm not sure for which Nintendo console) to make MIDI controllers.

Just simply amazing.

Well, that's for the visual element of 'electronic' music. Performing with those would simply give audience the 'wow' factor, but in my opinion, I believe it doesn't have much usage in making music sounds good.

But hey, electronic music is about experiments, isn't it?
