When I was spinning through the Internet Boom and Bust in the 1990s, cartooning was my "shadow career." It was a repository for all of my observations and angst. These days, I license them out to people to use in their books, presentations, and websites - I suspect often for the same purpose. Some samples are below.
NOTE: These are all copyrighted, and there are TONS more where they came from (over 2,000 to date). If you're interested in using a cartoon, you can contact me directly or you can also get my cartoons on CartoonStock.com (those guys are great.)
