Telegraphics - Free plugins for Photoshop & Illustrator...and other software
I love this guy's tag line: "Subverting the dominant paradigm since 1998." Clearly, he lives by what he preaches... must be a Martian! Anyway, the site is chock-full of useful design tools, including Photoshop filters, fonts, 3D models, and much more. I'll definitely have to drop him a donation once I have a chance to try some stuff out.
