A stellated dodecadron (aka dodecahedral star) made from 30 7.2x7.2cm units of construction paper. It's not self-stable so there is a little bit of double-stick tape holding the modules together. It's tri-colored, with no color touching itself along a side.
The pattern is from Miyuki Kawamura's "Polyhedron Origami for Beginners", although I inverted it because I wanted the folded details visible (normally each module looks smooth from the outside).
As always, comments, criticism, or advice welcomed.
