Animator Webster Colcord has been transferring old film footage to 4K digital. One of the reels had his animation which utilized a modified frog skeleton. Not a plastic toy - but from a real frog! Here is what he had to say about his involvement:

"This was a stop-motion sequence that I animated in 1991 for a Roger Waters music video directed by Tony Kaye. This was shot at Will Vinton studios and I worked under the direction of Mark Gustafson. I had this scanned in 4K recently from a 35mm workprint. Music here is by Lavender Hill Mob and is used with permission."
