In some model of LCD modules there is special film. The purpose of this plastic sheet is to distribute light. I think this plastic is embossed with some prism or other pattern like Fresnel lenses. Just look at the images:
The film likes to make images double. But only when looking from one side. From other side, the plastics looks like bad mirror.

Friday, June 3rd, 2005Gastroscope – weird stuff I have
Wednesday, June 1st, 2005Gastroscope: A flexible, lighted instrument that is put through the mouth and down the esophagus to view the stomach. Tissue from the stomach can also be removed through the gastroscope.
Cool toy for every man. 
It is very old, Olympus JF-B3 medical apparatus. Also I have special cool light source device. There is Olympus camera in the case, with special adapter to connect it to gastroscope. I am not looking inside any living human being, but used to examine various holes in my house. Also this device is useful to check vehicle closed chambers – to test the engine, or realise how your car is rusting from inside. The length of the hose is about 120cm.
This model has various handles and holes to manipulate the end of gastroscope. The main problem with this device that I can’t connect it to my digital camera. What nice photos I could make with it.
