My favorite display is the large hanging Snowflake made up of 216 RGB pixel lights. It takes longer to set up in the sequencing software (xLights), but once set up and each snowflake sub-model created (Vines, Branches, Inner Core, etc.), The effects I can create with them are far superior than say one roof line.
I have future plans for a Mega-tree, Pixel Matrix, and additional Light Arches that will cascade down the retaining wall steps.
