Fan-made stuff is always great to see, especially when it blows our minds with unforeseen levels of awesome. Steam user "Zachariah" posted a video made using the Source Filmmaker, dubbed The Turret Anthem, and we're absolutely floored by his efforts.
As the name pretty much implies, the short features a turret ensemble from Portal, singing to a disgruntled GlaDOS. Given how this whole thing ends, I'd say her annoyance is more than justified. Hell, you can't have turrets and GLaDOS without some level of creepiness.
Anyway, here's a little background on the video, which you can view after the break. Be sure to hit the source link for more behind-the-scenes stuff.
This video was shot on black void, using a rebuild version of glados' chamber that I put together by hand. Fun story about this video, I've been trying to make it for about 6 months, it's a super late Turret Week video. I kept overthinking it, and had much of the principal synchronization done but couldnt' figure out how I wanted to shoot it, well I sat down this weekend and knocked it out in two days, and I'm pretty sure nobody will have any problem with the results. The name of this video is The Turret Anthem, but throughout production I always referred to it by it's secret codename, Megadub, and so it sticks.
