I dug this up. I was working with 3VR, a facial recognition/physical security software company about 5 years ago. I was really only hired to do some layout work and update their user guide, but I ended up doing technical illustration for some of their other stuff, like this one-sheet installation guide. It was weird because I never considered myself an illustrator, but I guess I am - when it's anal and technical enough anyway. Give me a kid's storybook to illustrate and forget it. Give me server farms, I'm your gal!
