If you visit allow.webcam and, yep, enable webcam access, your computer will take your photo and add it to a collage of the prior snapshots.
It's surprising there aren't more penises and butts in the collage but maybe it's a signal that culture has shifted. Or perhaps the site automatically filters those out.
