Legend has it that, in the days following the Civil War, old glass negatives of forgotten soldiers were sold cheap to farmers to build greenhouses. As the light struck the frames, the faces of the dead would appear on the leaves of the plants and on all of the other surfaces of the interior. No one is sure if these were ever really built, but an artist and a class at Rensselaer Polytechnic did build one, using 100-year-old glass negative mugshots of crooks. In this haunted house, it's not so much the nighttime that's scary, but boy does it get creeeeeeee-py when the sun comes up. Pico-projected 12-megapixel digital mugshots of modern day criminals surely wouldn't have the same effect, but we'd have written that up for sure. [Make]
