Vertically Sliding TV Mount

[Ultima99]

So here's one I'm hoping you guys can help me figure out.

I need to find a TV wall mount that slides vertically and not with an arm.

All I can find is either arm models or very expensive, like $250+.

I found one! It's expensive and motorized... lol. There was some guy that worked for Google (or similar) a few years ago that had a sizable setup with game machines in a rack and all the IO out in his living room. That had what you're looking for and he had links to everything. I can't find it tho
