Participatory Origami reaches YOU. Go get an A4 sheet of paper NOW, here is a cracking model for you to try: Here is my first attempt, after hours of pre-creasing, unfolding and collapsing I think I have nearly mastered this model. It seems there are some complicated variations on this design, with subtle manipulation a plethora of other models are possible.
um… couldn’t you have just crumpled it in the first place?
…you did look at the DATE of this posting I assume?
Yea…so???
