Magnifying Glass Optical Illusion

Aaron from the photoblog Knurdle.com took this photo and presented it on his blog. He says the following about this picture and effect:

Neat trick you can do with a magnifying glass.
I was amazed when I was shown this and had to get a picture of it.

Seems to me that this must be similar to a film projector focusing an image on a screen. Everything imaged on the table seem to have their own light source. This effect can lead one to believe at first glance that there are two light sources in different locations, or a light box built into the table. It could take a few seconds for your brain to sort things out and give you an accurate interpretation of what your seeing.

Thanks again to Aaron of Knurdle.com for allowing me the use of this image.
