Over the past decade or so, Pi day, March 14 (3/14) had blossomed into a widespread celebration of pies and nerdiness. For the past two years, I’ve attempted to blend the pie and nerdy aspect into a single creation: a Geometiles pie. This year’s pie, shown above, had a scalloped crust and its own white stand. The construction of the stand pedestal used Mobies, which make it possible to fold layers of tiles so they lie completely on top of one another. This video of the pie being made turned out to be a very popular on Instagram. Here is the YouTube version:

The above “pie” turned out to be a polyhedron that I’ve never encountered before. I decided to call it “PIElyhedron”, in the spirit of the joyful silliness that is the modern day Pi Day celebrations. Here is the view of the Polyhedron from the top and bottom:
Last year I mad a rather elaborate lattice pie with tetrahedral strawberries:
It was a challenge to come up with a way to make convincing lattice strips. The bottom crust had to be large enough to support at least 6 strips, yet it had to look sufficiently round. The strips had to make certain angles with the crust, so some of them were square, while others triangular. Making this pie was a worthwhile challenge, because the “leftovers” were appreciated by middle schoolers at a math festival the next day.
