A light thingy hanging from the ceiling just on top of your pillow featuring a “Snooze” function that makes you physically wake up

When I first saw the photo I thought it gradually slid down and lightened up until it reached your head and a high level of annoyance, but it’s the other way round. “Sfera” actually turns on in the morning just on top of you, and when you switch it off with a smack, the snooze function starts raising the thing every time you smack it off… until you have to literally wake up to shut the sucker up.

Personally, my idea of the definitive alarm clock is something similar to this. It would be some sort of hook hanging from the ceiling to which you could cling to, letting IT do the physical effort to wake YOU up. Or a bed tilting onwards to the vertical.
