As part of a promotion for a Star Trek Convention in Las Vegas on August 17-20, a contest is being held with support from Google. All you need is to create a Star Trek-based 3D model with the free Google SketchUp and submit it to the Google 3DWarehouse with the tag “scifi”. The deadline is August 13, so get busy! The best 3D models will be displayed at the Google Booth at the convention. Here’s a news story about the contest from startrek.com. Here’s the Google page on the Star Trek contest.
