Check out the full progress photolog here. Or, if you've been in IRC, you've heard me talking about it non-stop for the past 2 months.

Wow. That's really impressive. How much longer until its finished?

Big Mood

I'm hoping to have it finished by March 1st.

awesome :thumbup:

Of course the real difficulty is going to be getting a Xen crystal to power it.

Why do people think the gravity gun is powered by xen crystals? Is there some official source that says this? Throughout the entire narrative of the HL series, the xen crystals have always been tied to teleportation technology. The reactor in HL1, in the Nihilanth's chamber (he draws from them when he shoots the teleporter beam thing), the rotato in Kleiner's lab, the full scale teleporter in Black Mesa East. I realize they are kind of the macguffin that drives part of the narrative in this weird fringe way. But at no point are they ever shown to have any sort of gravity affecting ability.

Beyond that, "zero point energy" is a real thing. In the movie The Incredibles, the main villain has zero point energy weapons which function almost identically to how the gravity gun works too, and is much more based on the realistic application of zero point energy.

Stylistically, I've always thought the Gravity Gun looks like these:

Which, if you're not a Stargate fan, they're zero point modules, a type of power source. They're golden crystalline batteries, basically. I'd have to go and see when the first reference to the ZPMs in Stargate is but I'm pretty sure it was before HL2 came out. And lest we forget, originally the Gravity Gun was going to be blue from the get-go.

I always just assumed it was a Xen crystal because of the similar graphics (this vs. this), although that might be because of the limited number of ways to make something look "sciency" in a game. But I never knew that zero-point energy was a real term, I had thought it was just technobabble like on the portal gun diagrams. Now I have to go research that a bit...

I will agree that the HL1 xen crystals look similar to the HL2 gravity gun. However, go back and investigate the HL2 xen crystals. It's most obvious in Eli's lab, it's the crystal material in the big container with the controls to rotate it, on the wall opposite of the telepad. It is very, very different looking from the HL1 counterpart but almost certainly due to increases in graphics quality (a good analogue is the vortigaunts in HL1 and HL2), but it's most certainly a xen crystal based on the material name.

This one? You're right, the wiki also calls it a Xen crystal in the article on Black Mesa East.

Yup, that's it. If you follow the architecture in that map, the energy it emits is a component to the BME teleporter.
