Parallelogram Pile
A sketch inspired by some lovely #mathart from @tilman: http://geometrydaily.tumblr.com/post/45757253199/399-ashes-of-the-triangle-a-new-minimal
It inspired a lot of questions: Are the parallelograms similar? What's the scale? Is it fractal? How would you construct it? Does it generalize?
