Red Ball 1, 2, 3 (Vintage Sesame Street)

[link] I loved this on Sesame Street, although I think it was a different version.  In the end there was no little girl eating a sundae with the ball as a cherry.  Instead, it became powder.  The synthesized soundtrack (which is like the Moog album I listed to a lot as a kid) seemed to really go with the film, providing a sort of atmosphere for this highly abstracted setting.  Cool stuff.
