Discovered a cool photography technique a while ago called "refractography". Basically, you are taking a picture of light scattered from a glass or other reflective object.
To do this, you get a beam of light, I used a flashlight covered with a piece of cardboard, then had a pinhole poked in it; point this beam of light at a refractive object (a scotch glass in my case), and then position the camera where the light is reflecting.
But here's the catch, you need to detach your lens from your camera. The light will be reflecting directly onto your sensor when you take a picture.
Also, you need to do this in complete darkness.
Anyways, here are my photos. And here is a page that might better describe the process of refractography.
