Hey Bowtieguy,
You are 100% right, it is my favorite! When I am using it to get patterns in it, it is like the lasers are my paint and the glass sphere is the canvas. When I am in the process of photographing it, I am using the adjustments on my tripod even so slightly and you can control the amount of bend and other attributes of what is seen reflecting around inside the glass. But if I get any bright reflections, it lights up the sphere(overexposes) in spots that destroys the photo for me. Trust me, for every nice shot posted here, there are many with imperfections, or different versions with or without certain colors. I always get everything set and exposed using RGB lasers, take some test shots, and if they look good, I will make adjustments on the camera and add yellow and violet
