My favorite dimming effect
It testing channel outputs and numbering during setup this year I "discovered" (read: stumbled upon accidentally) an effect that I then made into the centerpiece of a sequence. I had one of my sons running the show computer inside as my other son and I finalized the connections to the controllers. The son indoors was scrolling the intensity down to about 30% on my all incandescent end effects. It looked really neat to have everything on at that low intensity.
I made that into a sequence I use "between" shows as a kind of reset to distinguish the end of the program cycle.
