Or "Jeff's Portfolio Website" for short

What we have here is a collection of writings and drawings that document some of the things I have been working on over the years. This is mostly for fun, but I wouldn't mind if this helped me find some employment opportunities. I could give you my resume, if you like, but sometimes instead of giving my resume to a person, I tell him or her that it can be obtained by clicking on one of the hyperlinks on the front page of my website. Specifically, the one that says my resume on it.
