Quilting, Crocheting, and Math! Oh my!

I've had this idea for many years, to make a penrose triangle quilt. In the same way that you can tile a plane with equilateral triangles, you can tile it with (2D representations of) Penrose triangles. Just make the obvious connections on the edges, and you end up with what looks like an intriguing but impossible thicket of girders. Once you do this, you can see that the tiling, as a 2D pattern, consists only of triangles and trapezoids, and all of the trapezoids are exactly the same size and shape. (Should be different colors, though.) I hope to have an illustration of this some time soon, but anyway, it just seems like a very easy kind of quilt to make, for those who make quilts. It's only the edge parts that require any thinking.

Astoundingly, I couldn't find any examples of the tiled pattern that would make up the quilt that I want to make. I'll look or make or draw one. One problem is that this is a tiling made up of Penrose Triangles, but there is a better-known tiling of the plane (the (first? only? simplest?) aperiodic one), which is also due to Penrose, but is otherwise unrelated to Penrose triangles.

This makes it hard to google for the one I'm seeking, though it does relate to the quilting angle.


At any rate, all this reminded me of some wacky knitting I saw, where people knit 3D representations of mathematical surfaces and objects (Moebius strips, klein bottles, space-filling superfolded things, braided items, etc). Fun stuff.
Finally, I had to link to a list of wannabe entrants in the "Worst quilt in the world" contests.
