paper totem – Too bad the milk-boxes doesn't look like this!
Macaw by Anna Trundle. This one is such a beauty, a paper sculpture made of different irregular shaped tetrahedra. It is often mistaken as an Origami model, but as you can see here: http://www.theloop.com.au/trundle/project/169457 the pieces are cut out of paper and glued together.
