This is a video installation from German artist Friedrich van Schoor in which he captured footage of two spiders running around in a model of a room, then projected the footage in the windows of the ACTUAL room, so they appear giant. It's not for people who don't like spiders. Or video installations.
Hit the jump for the video. Photos of how the video was made until 1:20 when the actual projection starts.
Thanks to Evil Ares, who is so evil he's actually trying to breed giant spiders. You're sick!
