Hold up.... WHAT!!! / Awesome Product

Ok, I don't know if maybe this was just something that everyone knew existed but WHAT?! How long has this been around for!?
It's literally a light which projects a rainbow onto your wall. Called Rainbow in my Room. From UrbanOutfitters.
But really?!? This is possibly the most AWESOME (note the caps) thing I have ever come across in my long hours spent trawling through google for new and exciting products. Now I know as a theatre lighting tech in my spare time I am probably, just maybe, likely to get a little bit more excited about cool lighting than the average gal, but seriously, this right now has blown my mind.
Did anyone else know about these?
