I haven't had much time to really focus on anything, but I have spent more time playing with Processing. My latest sketch involves repeating patterns of Bezier curves in interesting fashions. I'm trying to make something along the line of Truchet tiles, but I'm a long ways from that.

Just posted my first processing app Gravity Flock. I spent awhile playing around and finally just decided to publish it, but I'll probably have a couple variants up soon.

Processing is pretty awesome. It really simplifies the process of building a Java applet and tosses in some fairly good graphics libraries, and I have really enjoying experimenting with it.
