Whew! Glad we got that cleared up.

Very awesome...but dern...you mean there is no Phi in crumpling?

(Of course, I know there are many folders out there who would disagree with
that conclusion.)
Well, yes, following one of your more complex crease patterns, the first 
attempt(s) might very well turn out quite indistinguishable from 
crumbling ;-)


I do use crumbling in some origami works, but mainly as a means to 
change the properties of the paper before folding.


The empirical discovery of Yamamoto and Yamazaki that the 
successive-folding process leads to a lognormal behavior sounds 
plausible. Intuitively the number of cells is doubled - at least locally 
- with each fold?
