Experiments in controlling LEDs using Guile + Arduino led-controller.scm is the current working daemon. It is licensed under the GPLv3 as it is becoming a "real" program and will likely be released on its own. picker/* are from the raphael js graphics library demos and are MIT licensed. They connect to the led daemon using GET requests to set the current color. fade3.scm, fade4.scm, and led-web.scm are hacks that gradually evolved into led-controller.scm
