I thought everyone in the FIRST competition might be interested in this:
X-CAD
These people are basically offering everyone who signs up a free license of their parametric modeling software (think Autodesk Inventor or Solidworks, except free). The catch is that 100,000 people have to sign up before August 1st; right now they're at 55,000. I know my team used to struggle with the single-license rules for the software that came with the kit, so this might be a good thing for low-budget teams.
