Blom (I) and Berner (Caitlin) invented the Behemoth (huge animal, extremely large, cumbersome or inefficient), a musical vehicle in the shape of a B. At home I have a seesaw, like the one in the playground. If you use the spring under the seesaw as a kind of accordion, sound is produced by going back and forth. The idea of using your entire body to produce sound intrigued me. A Rhönrad is a circus attribute, which rotates through the movement of the acrobat. Together these ideas form the design of the Behemoth, a Rhönrad where you sit on the curve of the b, which forms the seat. Bicycle bearings are put in the tubes of the B, and by rolling sound is produced.
