3 sets I have in my Living Room window for Christmas. Running on an A-B SLC5/05 with 2 racks, and controlled by 2 separate PC's and a Windows 10 tablet all running AdvancedHMI. The 7 element set across the top of the window is also activated for Halloween (with 7 cat lanterns) and Easter (7 Easter eggs). The display is programmed with separate start & stop times for November/January and for December. They are programmed to be on from November 22nd through January 3rd.
