This one, made from "scratch" reminded me of the Zulu shields that we learned about in school. The diamond part of the pattern is just about the right shape. Johnny Clegg also wrote a really cool song also titled Impi.

Today’s Gratitude Item: My Anti rain device (aka: a very large umbrella). It works by discouraging rain from falling. Taking said device on a walk almost always guarantees fine weather. Its fail-safe as well. If its anti-rain powers are not working at optimal strength and it does rain, at least I don’t get wet.
