For creative types, there is nothing more terrifying than a blank screen. If this happens to you (I know I suffer from this brain-drain syndrome periodically) then check out a powerful brainstorming tool called Moodstream from Getty Images.

Images, video footage and audio are available to provide inspiration for your creative. Users simply fine-tune their mood setting (happy or sad, calm or lively, nostalgic or contemporary) and choose a few preset indicators (intensify, stabilize, excite, inspire, etc.) which reflect their current mood and Getty pulls images, video and audio will detailed information making it available for purchase.

An excellent idea all around - the presentation of content and a stellar user interface is going to make MoodStream a phenomenal add-on service for Getty.
