I work on visual effects for film and games.
I sit in front of a computer and create a rig for a character that will be used in animation. I also simulate clothing and hair using the computer to create a physics environment. I'm surrounded by some of the best artists in the world.
Here's the first step for college students
Start playing with 3d animation programs, such as Maya, 3D Studio Max or XSI. Run through some tutorials online (there are tons). Because this work can become tedious, it's important to really like what you're doing. There are so many kinds of jobs in visual effects and some people overlap roles, so it's important to see which job you would enjoy the most and get really good at that one thing.
