I stumbled upon this video by Vincent Floderer demonstrating how to fold his mushroom. While you might argue whether it's still origami or not, it is definitely an interesting technique.
I'll avoid the discussion by simply calling it "crumpling". Anyone know what crumple means in Japanese? Google translate suggest: 揉む (crumpling) or 揉む紙 (crumpling paper).
