Been thinking about war recently (it's that time of year.. and the american elections bring these things home a bit too). War is the one complexity that we can't really deal with. There is little adaptation one can do, it is more infinitely complex than any attempt to counter with it. Unlike any other threat, including climate change, or terrorism (and terrorism isn't war). All we can do is to avoid it, and ensure some resource to regulate its complexity (armies). So this first improvisation is about war. The second is something lighter based on twinkle twinkle little star.
