Help needed: artistic DVD for kids mentioned in earlier thread

A few months ago there was a brief discussion on here regarding a movie/DVD, geared toward children I think, that sounded really good. The topic was something related to some artist or artistic idea (something like Escher - but I did a search on Escher and couldn’t find it); some sort of high-concept animated film. A few people here had seen it / had it for their kids and it was highly praised. It sounded perfect for one of the artistic kids in my life … can someone help me out? Sorry it’s so vague - that’s all I remember!
