Why ironic? I's say you have a head start on solving the quiz. I look  
forward to seeing your submission.

Nice images. The design you call Penrose, I call Hilbert. That and  
several other classic turtle designs (both the turtle code and the  
graphic output) are included with the quiz for participants to test  
against their Turtle class. The turtle code is in the samples folder  
and the graphics (.tiff files) are in the designs folder. Also,  
compare tree.tiff to your tree.png -- fairly similar.
