It's a really simple setup. I used different mp3-files to drive a curl noise inside a popnet. Some resampling in chops need to be done so that the curlnoise wouldn't jitter too much.
The baseobject are 12 cubes that are scaled down with the copysop. I used a softbody pop inside the popnetwork the get the whole mesh into it. The white wires are created with a fuse sop averaging the position of the other wires. The point sop is there to set the wirethickness for rendering (pscale).
