Sometimes simple ideas are the best. Like here: both song “A Merry Go Round in the Park”, as well as the visualisation are pure simple. There is also something special about the music itself. It’s from Lullatone, from an album with a very pragmatic name: Songs that spin in circle. “10 long loopable lullabies for babies (and adults).” I figured out for example, that you can open some instances of the video above without any problem. It keep enriching the sound instead of disturbing. Nice thing to tweak around with. (via)
Update: Oh, funny stuff. I found that on the Lullatone website: Instrument Exhibition!
