Withings' tuba-shaped Aura Sleep System is a strange and somewhat massive alarm clock that's just as concerned with luring users to sleep as it is with waking them up. That large hole up top is a large LED lamp that changes colors based on function, slowing down their system at bedtime and gently waking them up in the morning.

The system can also be paired with a sleep sensor designed to further analyze the user's sleep habits, slipping under the mattress to monitor breathing, heart rate, motion and the like in order to better adjust its function to put people to sleep and wake them up at the right time in their sleep cycle.

The big news on the Aura front at this year's show is the announcement of a Spotify partnership, making the device the first of its kind to be compatible with Spotify Connect, rolling the 30 million song catalog into its arsenal of sleep and waking tools.

The company is currently working on a recommendation system for sleeping and waking songs.
