Through the wonderful Wonderlands community I found out about the GUD competition. GUD is a spec-fic magazine that features art, flash fiction, genre fiction around a theme. GUD Magazine is preparing to launch issue#3, an issue that has Mechanical Flight as theme.
They're running a Pre-launch Buzz Contest, if you blog about their contest you are entered in the competition for A FULL SET OF GUD, HARDCOVER (Issues 0-3). You can find the full contest rules on GUD Magazine website. They have also two bonuses there and the full content of the third issue of GUD Magazine.
