The Summer of Sonic was a HUGE collaboration between the Sonic the Hedgehog online community, celebrating the blue blur's 15th Anniversary! Webmasters from Sonic fansites large and small, fan artists far and wide, comics and fiction the world over came together in Summer 2006 for this one cause. And many visitors joined in the action as well, by signing Sonic's Birthday Card and sending in their own contributions. It became the biggest and most important event the Sonic online community had ever seen. The website is now archived here.
