So there's a company which sells puppet patterns and supplies, one such pattern being the one I used as the base for Newton's head. They encourage builders to send photos of their creations to demonstrate some of the possibilities and variations you can make with their base patterns.

I sent them photos of Newton back in January, and guess who popped up on their gallery page today?

Yeah, I'm kinda proud of him, too :)
