@vskolnik It's actually a small vase that is amber cracked glass. I put it in front of my computer monitor and the colors are the different apps on my screen. MaryBeth @espyetta gave me a creative macro book for my birthday and he talked about using various sources for back lighting. Marloes @stimuloog also gave me the idea of using my computer screen. Thanks Vee!
