Welcome to Graphics Challenge 100! This week our challenge theme is Playing With Light.
We've given you a choice of four images to start with, use at least two of them in your new image.

I used the following two images from the four supplied.
Image #1: http://www.sxc.hu/photo/682180
Image #4: http://www.sxc.hu/photo/859563 .
Image #1: replaced the black background with a green background and used Colorful Center on it.
Image #4: removed some of the black background then used Crystal Ball and changed the blending mode
to Difference. Copied and pasted the Crystal Ball image into the first image, flattened the image, adjusted
the hue & saturation then used Soft Flat Color. I used PSE4 to make this image.
