I decided to do a few things in Photoshop for fun related to Black Mesa, That could be like products:
Black Mesa T Front:
BM T Back:
Black Mesa Basketball - Large:
Black Mesa Soda Can:
Black Mesa Stylish Mouse Pad:
Give me some more ideas. 
A white T? A hoodie? A belt buckle (Hell that would be awesome)?
Hubcaps.
What about hats ?
Maybe a bandana (I collect them), a crowbar toy, and a rubber ducky.
Now that I think of it, a rubber crowbar would be cool.
An HEV watch please.
How about a ridiculous tie?
Needs to also include an accelerometer and speaker (like a wiimote) so that, when you swing it about, it makes the Half-Life crowbar swoosh noise, and when you hit something, it makes the CLANG noise.
Damn straight!
I lol’d IRL. Well played. I must have a ridiculous tie somewhere… I’ll look for it and post a picture for inspiration.
[COLOR=‘Red’]raw_bean: your image link is broken, it has spaces in the file name and I can’t get it to work for you.
That’s the closest to the original I got.
Edit: Okay I fixed it. It’s strange because I could see it.
Laserpointers that shoot the BM logo, now that’s some stylish retinal damage.
Impressive work.
What no black mesa themed thongs?
HEV-suit hoodies!
This, but Mark 4, so there’s cool black shoulder printing.
Would go nice with the thick-framed retro glasses we all bought on impulse to replace out regular glasses.
we all DID do that, didn’t we?
I did. Well, kinda. My glasses are grey and not THAT retro, but I wouldn’t mind changing them next time I visit the ophthalmologist or whatever it is they are called.
I don’t wear glasses because my vision doesn’t suck.
