Portable Blender
I'm a freshman at Cogswell Polytechnical College in Sunnyvale, California majoring in Digital Art & Animation. I want to specialize in 3D modeling, yet there's a ton of prereqs in order to begin modeling classes. Screw curriculum hierarchies, I'm gonna teach myself for now. As Softimage|XSI and Maya are expensive packages to get my hands on for learning, I've started using Blender.
During off-time at school in between classes, I want to use school computers to practice more on Blender, yet you need administrative privilages to install Blender and python, and frankly it's going to piss the IT guys off if I'm installing Blender on the Photoshop lab computers and so on.
