Ryan playing the...organ?

I think that thing is an organ of some sort. It's at the OMSI. Kids are constantly playing around on it, making lots of noise. We were standing around looking at other things when I suddenly noticed that amongst all the noise there was a real song (with other kids continuing to make random noise on the upper end, I patiently waited for them to be done before taking the video). I've taught the boys a little bit on the piano, and apparently Ryan has memorized Twinkle Twinkle Little Star! Only not just the notes on the piano, the intervals between the notes. Pretty impressive for a five year old, huh?!?
