Aaron Wendel, one of my instrument construction students at The School of the Art Institute of Chicago, has a video up about his very cool and unusual Bubble Organ. Watch it on the Gearwire website: http://www.gearwire.com/bubble-organ-lab.html
For a demonstration of my own instrument invention, the Springboard, watch the four videos on Gearwire:
An in-depth text description of the Springboard will be published this year in the Leonardo Music Journal, and another version can be found here on the “experimental instruments” page.
