The stable figure took around 30 minutes, the ambiguous took around 45 minutes. I chose this stable and ambiguous to my final project, because these two design is simple to show what I understand of the meaning of stable and ambiguous. Compared to phase 2, it was hard to cut and difficult to make each side looked like the original drawing.
very cool, i see a face in the ambiguous figure. For the stable figure, I’m not very sure what it looks like, but I can see its pretty stable.
