I've been playing around with Inkscape for some art projects recently. It's free and works great. It has a function that can convert a bitmap into vectors.

Alien Skin through their Snap Art product has a number of filters that you can apply in say photoshop. I have a set that I posted up on Flickr. part of the set I took a photo I had of Sleeping Beauty Castle and added each filter with the default settings. They have some really good stuff!

Welcome, Frikitiki! You a friend of GC?

More importantly, are you a foe of Gn2?

Oh yeah, I should know that. Just in case.
