There was a similar origami simulator that I saw from hn a while back:<p><a href="http://www.amandaghassaei.com/projects/origami_simulator/" rel="nofollow">http://www.amandaghassaei.com/projects/origami_simulator/</a><p><a href="http://apps.amandaghassaei.com/OrigamiSimulator/" rel="nofollow">http://apps.amandaghassaei.com/OrigamiSimulator/</a>
