Oops, forgot to answer the avatar Q!
When I put together my 5U modular synth, it took me *forever* to get power distribution working. I had modules sitting in boxes for over a year. Off the shelf power options are expensive, and being broke didn't help much. I finally found some old linear power supplies at a surplus place, and salvaged some fused switchpanels from other dead electronics.
5U modular format is also called Moog Unit ( MU ), in reference to Moog, who pioneered a lot of the modular synth designs.
I have always had a humorous affinity with cows, for multiple reasons. Growing up near a cow field led to many disasterous & fun adventures. I keep running into Cow references & anecdotes throughout life: and a video game I did a soundtrack for is also full of funny cow references.
So I needed to come up with a name to use. As a pun on MU ( Moog Unit ) and how long it took me to actually get the damn power distro working, combined with the cow humour, I chose "Electric Moo".
So that avatar is a shot of my 5U/MU modular, with a cow skull in the foreground.
And to top it all off, and celebrate the fact this thing actually works now (!!) I am currently working on a modular album called "Electric MU"
