Last week Google introduced a brand new ad format to their AdSense collection - the Google Gadget Ad. It differs from existing formats in that it's interactive, allowing the person viewing it to play a small game, perform a search or similar. The idea is that they'll provide better value to AdWords advertisers and benefit AdSense publishers by keeping visitors at their site for longer.
If you're ready to start displaying gadget ads on your website you can increase the chances that they'll be shown by making sure you're opted in to image ads and using one of the image ad formats. Please note that the most popular sizes for gadget ads are the rectangle, leaderboard, and skyscraper formats.
