We prepared this video for the Fleming School 5th Grade Assembly on 6/8/11

 

While the inventor-rider is not a BMX practitioner, and the prototype is a road bike, you can see here how the design lets you 'dance' to beats other than disco, offset the pedals to the outside of a turn to do figure-eights under power, and take your choice of longer, slower strokes or shorter, quicker ones at any given road speed. Since there's no 'dead spot' (when rotary pedals are at 12 and 6 o'clock), it ascends better than any single-speed rotary bike with equivalent gearing. 

    Here's the link to the story in the Burlington Free Press after the 5th Grade Assembly.
