this beats out the guitar hero bike video..



but perhaps even better is this comment..

"Dear Honda Engineers,
Your song is out of tune (the opening interval is a semitone flat, the top note is a minor third too low, etc.). I have a theory as to why: You started with a 4in spacing between 1in grooves. To change the pitch correctly, you should scale the whole 5in unit (spacing AND groove). But if you just scale the spacing, you get the wrong interval: (3+1)/(4+1) gives a M3rd (5/4) instead of 4th (4/3), and (2+1)/(4+1) gives a M6th (5/3) instead of octave (2/1)."

gotta love the internet.
