Playing with arguing pleats, I scored a sheet of card in random/odd verticals that were all a bit slanty, then accordioned it up to create the basic structure. Next I started creating a series of ziggy-zaggy inside reverse folds. in steps down, then steps back up.

The shadows of this thing really float my boat – I must explore if there is a way to control this some more – I am sure there is a method that allows me to create a path of fan-fold collapse that is curved.
I call this broken because this looks like a rip in space time (well, to me it does).
