Which platform game is it, for the PS3, where everything is made from fabric?

Question

I saw a trailer for it on a gaming programme, but can't remember the name of it. In the trailer the characters were pulling woollen balls and throwing snails onto a counterweight to open a door. Everything seemed to be soft and squashy, and the textures were really realistic! The clouds were soft. I can't remember anything else, sorry! I THINK it was for the PS3.

Answer 1

Little Big Planet.
It looks real cool, but not out yet.
