Starts With a Triangle
Ethan Siegel of "Starts With a Bang" blog regularly writes excellently on physics topics, but recently did a fine post pertaining more specifically to a geometry puzzle that often winds its way around the Web (...counting the number of triangles within a triangle):
a YouTube explanation for the same puzzle is available here:
Though he doesn't discuss it, Ethan's post actually starts off with a picture of the Sierpinski pyramid, a fractal-based object (which approaches a surface area and volume of 0) that is likely even more fascinating than the puzzle he is elucidating.
