Newgrounds.com — Everything, By Everyone.

Daniel "f00d" Weisman, a member of the Star Syndicate (which has been on hiatus with flash for about a year), just started a weekly collaboration which will be known as Syndication. The collaborative series will be released every week with new submissions from hopefully various artists who can showcase not only flash submissions, but also film, traditional animation and other mediums.
