So where are all the theremin accessories? With thousands and thousands of Etherwaves in circulation, surely some creative and industrious person has an idea out there... Perhaps a fine knitted Etherwave sweater? Antenna polish? Clip-on music stand? Play-from-batteries kit?
So far, all we have is a nice cat costume for the Etherwave.
As an incentive to everyone to help build this market, I will give front-page exposure to any theremin-related accessory (provided it's in good taste, of course).
Let the creativity begin!
