ToxicPurity's Top 20 Geeky Things

Okay, in response to Skribe's Top 20 Geeky Novels, and with no thought whatsoever, this is my list, in no especial order, of what I consider the top 20 Geeky Books/Films/TV/Whatsits Of All Time:

1. Monty Python - any/all
2. Douglas Adam's Hitchiker's Guide radio/TV/novels/towel...etc
3. The Rubik's Cube
4. 2000AD comics (pre-colour, before DC and Marvel poached all their best talent)
5. 60s epic SF Films With Something To Say (Planet of the Apes, Alphaville, 2001: A Space Odyssey)
6. Star Wars IV: A New Hope (Han shoots first, damnit!)
7. J.R.R.Tolkien's The Lord of the Rings (without whom the entire fantasy genre would not exist and to whom all subsequent fantasy authors and gaming entites owe their livelihoods)
8. William Gibson's Neuromancer (when SF became cool)
9. Alan Moore's & Dave Gibbon's Watchmen (when the comic book became the graphic novel ie. serious literature)
10. Neil Gaiman's Sandman series (when comics became cool)
11. Thunderbirds
12. The Prisoner (there was, and never will be, anything like this again)
13. pre-CGI-era film special effects (all hail the immortal hand of Ray Harryhausen)
14. Ultraman (and basically anything the Japanese mass-produced for kiddy TV really)
15. BBC SF TV (from Quatermass to Dr Who to Blake's 7 to Red Dwarf)
16. Superfriends (and other cartoons produced by Hanna-Barbera, without which Harvey Birdman: Attorney At Law wouldn't be half as much fun)
17. Star Trek (the original)
18. Computers (both imagined and actual, the more blinking lights the better)
19. Robots (this should be a Top 20 list all by itself)
20. Dinosaurs (mythical monsters that really existed? Sure geeky)

The thing is, what is "geeky"? Is it something like "cool-nerdy"? It seems to imply a combination of weird attractions and specialised interests and an appreciation of obscure knowledge. Can't think of any geeky music, though.
