Pinterest and Houzz are SO gosh darn addictive. LOVE THEM. Also google image searches help a lot when you're looking for a specific project or colors (searching "Blue and Yellow Bathroom" or something like that helps a lot.
We just redid our kitchen, and I got a wonderful idea to gut a nearby closet (in the middle of the dining room/hallway...odd spot for a closet) and create a bar! It has totally changed that area and I love it -- and the inspiration came from google!
I have a pinterest board called "cool rooms" that i just keep pinning all the neat ideas to. Both pinterest and houzz have ipad/iphone apps. can't tell you how many times i've been in bed flipping through them and glanced at the clock to see that HOURS have passed! =)
