BLIK

Design for those who like to change their minds. Really, that's roughly how this design product is advertised. Or "stickers for grown-ups". I mean, who woudn't want to decorate their house with giant stickers? This feeds in to the article I was reading recently about how to decorate your cube.

They are quite cool decals with the added value that you can peel them off (good for offices where you get moved every year or so). You can choose from a variety of themes and plan your design according to your taste. They have clouds and robots, geometric shapes and heads, organics... They sound like a lot of fun.
