It tries to get you to enroll in a school or something, so don't give it your email address or anything, but it's interesting and appears fairly accurate. Here's my result (along with a description of the test):
The Dewey Color System® is now the world's most accurate career testing instrument. This report based on your personality traits indicates your two most enjoyable day-day-day occupation skills. It’s a summary of the full report, the Color Leadership Evaluation 5.0.
Studies indicate workplace enjoyment is the key to success. So as you read, consider only "Was I mostly having fun at work?" Disregard your present and past employer’s environment.

You're a DOER
Keywords: Emotionally Stable, Reliable, High Energy, Practical, Thrifty, and Persistent
These adventurous types prefer action-oriented, concrete problems rather than dealing with thought-provoking, ambiguous, abstract dilemmas. Fields of interest include mechanical, construction, and outdoor careers. They might also enjoy working with machines, tools, and equipment to repair or build something.
I think people who know me would see it as pretty right on. Given my current occupation as a software engineer, I fall pretty close to where it looks like I should be - a mix between creator and doer. I kinda wish I had a little more in the way of "unstructured, flexible organizations" to deal with, but... well, them's the breaks.
I wanted to be 3D modeler/animator at one point. That would have been along these lines, too. Hmmm.
