The Tonematrix game is very hypnotic. The tone reminds me of Balinese gamelan music. Easy to get lost in the flow and polyrhythms.

The map game is fun. I do pretty well, it amazes me how many people can't manage the basics, like find China. I get thrown because the names have changed since I learned the map way back when we were still riding dinosaurs and everything was arranged along the lines of USSR versus NATO. I can never keep the East African nations straight.
