I'm well aware that most members on this board are certainly not the kind of Sonic fans that appreciate the Sonic fan community in general and the various flash movies and other tributes to the games that have been made over the years.
But still, i think some of you might enjoy this nice little Sonic/Fullmetal Alchemist flash i stumbled upon today during my daily NG visit. It's really nothing more than the Fullmetal Alchemist opening movie with the characters replaced by the Sonic cast, but it works well and is actually pretty stylish looking:

Full Metal Sonic
Like I said on another board, Shmorky's Sonic cartoons blows this away.
