If you haven’t already seen Auditorium – I suggest you go http://www.playauditorium.com/ now and play. Just stop what you’re doing and go play. Epic little game where you need to force particular waves into little boxes. When the boxes fill up they start to play music. Fill all the boxes on the level and you’re onto the next!
After the level finishes, the boxes and your little items (that change where the little waves are going) fade from the screen and you’re left with the pattern behind. Got this and it made me laugh. Not sure if that confirms I have to get out more, but it’s epic all the same.
