Peter Callesen

Peter Callesen is a Danish artist born 1967, and he does a lot of cutting out paper and making really cool sculptures out of it. The level of detail that he puts in the sculptures is really amazing. Somehow he manages to create these beautiful sculptures out of one piece of A4 paper.

I don't know if there's much information about him, but here's his website, and some pictures:
