For hilarious and sadistic kicks, German designer Friedrich van Schoor created this projection mapping installation of an entire building story occupied by two automobile-sized spiders. Oh, to be a fly on the wall confused passerby when these eight-legged monsters began scampering.

You can watch how van Schoor created this piece in the above video. Incidentally, this isn't the first oversized-arachnid-related optical illusion to hit the scene lately. Science artist Marlin Peterson recently created these trompe l'oeil paintings of harvestmen (or "daddy longlegs") atop the Seattle Center Armory, right underneath the Space Needle. That's more fodder for your Phoenix Jones fan fiction right there.

Hooray, an optical illusion of a building filled with giant spiders
