AutoDesk is giving away free copies of its student programs like AutoDesk Inventor. If you are a student you need to take a minute to register for this great offer! (visit Student Autodesk)
As soon as my month-long fight with my computer-box is over (Curse you SATA, Cheap Video Cards, and ECS Mobos), I plan on releasing some Inventor tutorials and because it is a $4000 program (Full Version) this maybe your only chance to grab a copy!
Please note that you must be a student with a college email address(I think they also allow Highschool emails). Also, you will need a decent video card for this program as it is a 3D modeling program. (64MB video card should be fine - but I suggest a 128MB.)
