Paper Castles and sorry for the blank lines ;-)

Peter Calessen is an artist, 

 renowned for his exceptional talent in combining the minimalism of a big crisp white sheet of paper with the complexity of meticulously cut and folded paper and uses the two to build out some really beautiful compositions. (Wikipedia)

I really like his works, her some examples:
