I went ahead and made the order to OSHPark this evening but made two small changes:

Decided I was being too timid and went ahead and connected the back copper to the ground plane with two small traces. I should be able to cut the traces if it screws things up but I think it will be OK
Determined that I had the volume pot hooked up in reverse and changed that

This is what the renders from OSHPark look like:

This is a great idea to fill in available space on PCBs. It looks really nice in the renders.

Hi Frank,

Very cool : ) Very apt to use an audio amplifier for this artwork : )

The design looks really nice. The '386 is a great chip.. I like the 'what were they thinking' crazily-high gain it can be configured for, ideal for test amps : )

Brilliant! Very creative. The art matches the function. I think it's great.

I will probably breadboard the circuit this weekend to see what the scream sounds like.

So far the artwork is looking good. It would be interesting to integrate the artwork into the actual circuit (either as traces or ground plane). Keep up the good work!
