I am totally flabbergasted, this is beyond awesome !
I want one ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
WOOT! Are these like giant, loose and extra-bold guitar strings? Must be hell for neighbors. Put me on want list!
The long loose ones are springs, and they provide the delay effect. Size difference of the drum like parts also gives the variability in the effect and they also act as membranes to distribute the sound. This can make some really cool sounds when you add more of those drums or add means to mess around with the springs, or you attach different kind of "instrument" to the pole where the guy does some violin action lol.
