Last night I got started using Spacebrew. It was actually really nice to use once I got everything setup and configured. I ran my own node server and used the example processing sketches to change the greyscale background of one sketch using a slider from another:
I then spent a good bit of time trying to get the arduino sketches to work with a leonardo + Wifi shield. I wasn’t able to get it yet, unfortunately, but I think I’ll have to dig into the source of the websockets or arduino spacebrew libraries (or both). I’m looking forward to trying this out with other projects!
