DesignBoom

I came across this website a few years ago, it mainly concentrates on industrial and product design competitions. Participants from around the world submit 3 images of their designs on a specific category, and it is then judged by a panel of architects and designers. The prize for each competition ranges between 1000-5000 euros. If you go to the competition section and look under the results for each of the competitions you can find the archives of all previous entries, very interesting. Another section on the site has informal interviews with around 100 top architects and designers which is also very interesting as it breaks away from the commonly asked questions in interviews and reveals their real personalities.
