Colored Shadows

Nifty new hands-on science museum here in Omaha - Kiewit Luminarium. This kid was projecting colored shadows. The light sources are only three colors: red, green, and blue. ". . . When the three colored light bulbs all shine on the same surface, we see all the wavelengths from red through to purple, which we perceive as white. With these three colored lights you can make shadows of seven different colors: blue, red, green, black, cyan (blue-green), magenta (pink), and yellow." From Science World

BetterPhoto Websites: If you see an orange website link directly under the photographer's name, it's totally okay. It's not spam. The reason: BetterPhoto is the one that offers these personal photography websites. We are supporting our clients with those links.
Unavailable EXIF: If there is no other information but 'Unavailable' in the EXIF (meaning no EXIF data exists with the photo), the 'Unavailable' blurb is not displayed. If there is any info, it shows. Many photos have the EXIF stripped out when people modify the image and resave it, before uploading.

I hear, I forget.
I see, I remember.
I do, I understand.
