I'm just curious if anyone on here has used the Processing programming language (also known as Processing.org and P5)? The reason I ask is that I'm a member of a hackerspace here in Birmingham and it seems to be quite popular amongst art and electronics people, we have held a couple of workshops on it. It is easy to interface with the Arduino based boards which is why the art people like it, they can create interactive works quite easily. It's built on top of Java and makes it really easy to create visual programs using 2D and 3D graphics as well as sounds and file manipulation. I was just curious if anyone here has done anything cool with it?
