Dream recorder v1.3 is an OS X app that analyzes your sleeping patterns by taking video of you while you sleep. It can then predict the optimum time to wake you up in the morning, gently remind you when you are probably dreaming (as an aid to practicing lucid dreaming), and also acts as a simple dream recorder.

“Dream recorder measures your sleep states by detecting your motions all along the night, using a enhanced night vision mode for iSight cameras… It wakes you up at the best moment of your morning sleep cycle, and provides dream feed-back and voice recording capabilities.”

I’ll have to borrow a webcam and give it a try (although I have a feeling I’ll be sleeping on the couch if I point a laptop screen and camera at the bed…)
