Along with all of the great examples available on the (newly re-vamped?) OpenProcessing site, I stumbled upon this inspiring collection in Tumblr – “Experiments in Processing”¬†http://p5art.tumblr.com/. I’m not sure who’s responsible for the site, and there are many sketches that are quite similar to those posted on OpenProcessing. But for me, this is a particularly attractive¬†group of intriguing experiments to explore and learn techniques from. In particular, the fireflies example turned me onto Dan Schiffman’s “Metaballs” coding challenge tutorial on YouTube – high on my “must watch soon” list.
