Decent *free* plug-ins? Do tell! What, where, etc?
The two third-party plug-ins that I'm particularly fond of are Blade-Pro (raised glass, mirror or chrome/metallic effects) and India Ink (Black & White ink pen cross-hatching effect), both from Flaming Pear. Neither are free, but everything I've seen from Flaming Pear is well worth their relatively low prices.
Scott, that's one I've had bookmarked as well, it's a great resource. Wow, quite a bit added since I've last been there, better go back soon. :) The Kangaroo filters are pretty cool. Also use Blade-Pro and *really* like it.
Oh, I adore BladePro... when I first got it, everything I did was either chrome or gold-plated. I couldn't believe it did such a good job with metallics. But I will defeinitely have to clean out some hard-drive space on my home machine, and start experimenting with some of these filters.
