I've long had this idea for a new alarm clock that would monitor your sleep cycles and wake you up during a cycle that wouldn't leave you grumpy all morning. Unfortunately I never did anything about this idea because
1) I don't know anything about sleep cycles.
2) I don't know anything about brain waves.
3) I don't know how to sell things to people who don't want to wake up grumpy in the morning.
Now someone has already made one of these. Oh well. Back to working my Jump To Conclusions Mat.
(No, I'm not going to buy one).
