I saw this vid of a guy playing guitar very well with just his toes...
But yea, doing piano seems a bit harder... because with guitar, you can tune it to fit your method... It's a bit different with piano.

I'd actually like to see a vid of this toe piano guy.

Somebody give that fucker a record deal.

I tried searching for good piano toe-playing on YouTube but most of them are pretty rubishy.

I've see a toe-playing guitarist who actually sat down and held it as a regular guitar, but with his feet. I don't even know how he got the dang things in the position that he did.
