Go to sleep while listening to comforting starship engine sounds

Why sleep listening to white noise or ocean sounds, when you could hear the Starship Enterprise in flight? Or the interior of the TARDIS?

That's what this new free app Hypersleep offers. (It's 99 cents for additional starship engine sounds.) I know I'd sleep a lot better if I knew that Data was still working on the enignes while I snoozed. [via Cult of Mac]
