Jennifer Culp is a writer, makeup artist, and now, a forger of human nightmares. That's because she created a Halloween makeup tutorial on how to make yourself look like you've been passed through Google's Deep Dream generator. If you're not aware, Deep Dream is a horrifying bit of technology that takes pleasant photos and makes them look like they're on bad acid (or good acid?) by replacing shapes in the photo with creatures that look like them (so, for example, the edge of a cloud that looks like a dog's face actually becomes a dog's face).
