Light only coming from an itouch
Light from an itouch and some ambient light from a tv.
The image below has ambient light from cfl light bulbs. The light from lower camera left is my computer screen. It eliminates the shadows from the overhead lights.
These were taken at night with just available light. The key is to underexpose the images. The camera will want to brighten the photos to make the scene look like daylight. So turn down the exposure settings so your camera is under exposing the shot.
