Vanishing Point - Week 1
With the combined brainpower of those from Neowin and Unifiction working together, all 12 puzzles released in the first puzzle box were solved with FOUR hours. Some were even solved without the help of the video (since it was released 2 or 3 hours after the event), but with descriptions of the pictures from a player on site on Las Vegas.
The video that was played in Vegas was actually quite clever. The use a fountain/light show along with actually projecting video onto the fountain streams itself to give the clues for the first puzzle box. The first puzzle box and the video from Vegas is live on the game site.
