I wish the direct weblink would be more informative, but going through the github, I noticed it is still building towards a more perfect piece, especially since it is community oriented.

Along with titbit messages hiting towards going to sleep, I hope it has an option of auto-airplane mode or blocking few websites after a chosen time-period...to help the slackers :D
Also a work planner would be nice, which could recommend daily sleep patterns according to workload of the day
and finally a full analyzer of sleep habits would be really cool, especially if you really want to work on your sleep habit
I hope they call it anti-alarm LOL
