Back in the early 2000s I was inspired by the work of Eric Levenez and his work on getting a UNIX family tree going. I actually had an early version of his tree printed out and on my wall in my first office ;-). I started collecting information on as many operating systems as I could, and I started doing a mashup of his work and other information I could find on the web. Somewhere in 2004 I stopped having a ton of time - and my original Omni Graffle files got lost in a hard drive crash. Yes, I had backups, but those eventually failed, too, by the time I had some free time. In any case, my interests at the moment lie elsewhere, but if anyone else wants to pick up where I left off, feel free to use these files. My OS Tree and Linux Trees are under CC-BY-SA license :-)
