If you love to do a bit of graphic design now and then (read: all the time) then www.premiumpixels.com, by UK-based web designer Orman Clark, will surely be worth checking out. I can't believe I only just discovered this website!
It's an absolutely fantastic resource for the creative individual, offering tons of free downloads ranging from PhotoShop brushes, layer styles, textures and patterns to documents and templates, and much more. Signing up is free, and from there you can download as many goodies as you like! I'd thoroughly recommend it!
