i think the source is available somewhere. certainly you're not the first to ask.

anyway, is random (moving) translucent circles. with lines joining their centres (if within a certain distance). all possibly using nothing but things in the processing reference.

is a useful thing to code as you can do it in steps, circles first. make them translucent. then make them move...

@kooogy - thanks for the reply, i appreciate. i'm going to dig around for the source, at least to help me get started on more understanding, if at all possible. if you know where the code resides (or anyone for that matter) - please point me in the right direction.

www.processingjs.org has a similar heading and the code is available.

Openprocessing.org has some sketches on there as well but I would have to look for them.

@owaunz - Thank you. I appreciate the help and direction!
