Treat #1 is datajunkie, by a guy named Hyperdave in S.F. As in Science Fiction/San Francisco. His pleasing yet disturbing online collection of pop geek memorabilia includes Outer Limits episode/monster trading cards, covers of vintage Popular Electronics and Psycho Comics.
Go, enjoy. Me, I'll sit here alone. In the dark. With the heat off. But don't you feel guilty, you, go enjoy yourself.
Now if you really want a geekgasm check out Comic Book Cover of the Week Club. If you happen to go the week I'm writing this, the choice of the week is the bizarre and omnisexual Boy Comics No.9. Don't stop there, be sure to enjoy the touching nuclear tableau (boy, dog, A-bomb), the classic Dell comics Brain Boy cover, or "Buckskin Battles the Banshee" in Super-Mystery Comics.
Treats for the treat.
