I recently finished reading Someone Comes to Town, Someone Leaves Town and have listened to his reading of When Sysadmins Ruled the Earth. I am now reading Down and Out in the Magic Kingdom. Weird, fantastic stuff.
What is more incredible is that he releases all his works under the Creative Commons license. You can go download it for free. If you like weird, technical fiction. Check him out.
