I'm trying to define solid shapes and manipulate them, and base them around arcs and circles. I'd prefer not to use shapes generated in Illustrator, as it would be easier to apply transformations to their outlines and parts if it were entirely parametric.

I've used Processing for a while, but I'm relatively new to linux. I can't find an INSTALL file or a readme in the source, and when I used sudo apt-get install proc[TAB][TAB], it didn't show any packages relating to Processing. Can someone give me a hand? I'm using Ubuntu 10.10, but if I've left necessary info out, lemme know and I'll be happy to post it.

I'm building a little device with my arduino to pulse LEDs along with music being played, and I want to know how Processing can listen to all audio leaving my computer (including stuff like iTunes and streaming online content) and process that. While playing a song within processing and have the arduino react, it's still rather limited, and my goal is to make this run all the time.
