BTW, sorry I haven't paid much attention to this thread:

I LOVE the switch to the blue instead of the yellow. Before I could get woken up by an errant movement when not nearly in the light sleep stages due to the alarm triggering by the 'yellow' accelerometer value. The blues do a decent job of approximating my sleep, at least.

Also, I noticed the new UI approach when you first implemented lucid dreaming / wake up stuff, and that was pretty neat.
