Excellent idea for a thread Joe thanks. I smell a 'sticky' here.
I'm also going to add one myself, and i would like to see others post links to the same kind of thing here. Let's see if we can really jam this thread full of good stuff.
NOTE: try to keep the links relevant to 'free' stuff for photoshop ok? Thanks!
Here's my link: A Brush Search Engine (
not just for Photoshop btw)
