'This is Aperture' music video channels The Nightmare Before Christmas

This past holiday, while we were busy sipping eggnog and chorusing the neighbors with classic holiday tunes, a group of dedicated Steam forum members were creating an incredible Christmas music album featuring Valve characters. "Goodbye Christmas Caroline" spawned more than an album, though, as one especially holiday spirit-filled member then crafted an entire music video around one particular track.

"This is Aperture" takes the characters we've come to know and love fear from the world of Aperture Science and recasts them as singers in a magnificently dorky rendition of The Nightmare Before Christmas' "This is Halloween." Take a look at the rather impressive re-creation above and then compare it against the original just after the break! Consider it a late holiday gift from us to you, but, ya know, one that we totally didn't make.
