Oh. My. Word.
Check this amazing site out. I just stumbled upon it while in the middle of some research for an idea that (inconveniently) popped into my brain at 1:30 a.m. EST. This always seems to happen to me. I nearly give up on the whole concept of designing for profit, and then WHAM! it hits me after midnight, while I'm trying to sleep, and I can't do anything (including that much-coveted sleep) until I have ridden the wave of inspiration wherever it leads me.
Haven't yet gone over all of the site, but it looks yummy for designer types like me to drool over. Hee hee!
