It was about a company that had a huge screen which would display photos and you could move them around like a Kinect (and other awesome stuff). The screen would be cool for an event I'm planning...<p>Thanks in advance!

Sorry, these are all I could think of. I know there was this startup in Silicon Valley that did something with gesture based music control and I think they got acquired by Microsoft, but I cannot recall their name right now...sorry.
