I've never found the latter, the best way to do that is with a 1970s strobe
light.
Which brings us to the apparent epidemic of outside animated illuminated
inflatable xmas decorations.
I can't see them these days except from the hue or auras from the lights.
For one thing, if these people want to save the planet is all this
electronic gadgetry really the way to proceed? Then there is my pet hate.
Animated Little Drummer boys.
Where in the Christmas Story is there a drummer boy? Not that Santa his
reindeer and flashing icicles have a lot to do with it either!

undulate. But why Flashing ones??
