This plugin adds a lightsensor to the range of redstone gimmicks. It is easily created by placing a lever under a glass block. This lever will switch when the the glass is lit adequately or not.
For example, you might want to use a lightsensor to lock your construction down when it is night.
Any feedback is more than welcome!
