Wanna see something cool? This player piano and a couple of robot percussionists are playing Nintendo music and sound effects while the game is played. Yep, this isn’t synced. It plays the sounds as you play.
The YouTube description explains thusly:
This system allows for Nintendo gameplay audio to be played through an acoustic player piano and robotically controlled percussive instruments. The piano and percussion play live during actual gameplay, mirroring the sounds that would normally be created electronically. All audio, including music and sound effects, is translated in realtime so that it is produced by the instrument most closely resembling the characteristics of the original electronic sound.
Neat, huh? Check out the video after the break.
