Lookin' for interesting content

[Vortex]

I'm looking for the best screenshots, beta content, mods etc for HL2/HL1. Remember it doesn't have to be those three things. It just needs to be content mainly.

I'll start:

http://www.moddb.com/mods/half-life-zombie-edition/images/screenshot-14

Yes, I know it's a website of screenshots from Half-Life...
