I admire people with patience, I have so little of it myself. I've made many works of art in my life, but very few of them took over half day to make.
Peter Callesen (oh, he is Danish) also makes large papercuts.
(I can't seem to make a direct link. Click on "large scale papercuts" on the left.)
One wouldn't imagine it would be the same man who would make bizarre and funny performances.
