Futurama Electroflux Theremin

In Season 6, episode 106 of Futurama "Ghost in the Machines" there is a quick flash of Dr. Zoibgerg playing an "Electroflux" theremin.

Still haven't found out who plays theremin for that show, could be a synth.  But at least they put the word "Theremin" out there this time.

Thanks Futurama gang!

Hi omhoge, I just started and I got a few questions regarding theremin if you don't mind.

I saw the schematics you uploaded under the name "Another Theremin Circuit" and I am very highly interested in building it from scratch. I was just wondering if you can recommend me some vendor stores to get the components from? 

Thanks man! really Appreciate it!
