What's Classy to some is Tacky to others. Just like a paint job on a house.
What if everyone had these lights. With no controls, hours, colors, flashing limits the place could look like a carnival sideshow.
Could someone leave up their "Christmas lights all year," Some might say no because they are Christmas lights. But one could argue that they are simply accent lights. How about some flashing blue, red and yellow lights to make sure everyone one feels safe since help is nearby. Another Idea , how about some background music to accompany the lights.
My son just returned from Japan and showed us a 3 dimensional display on a house showing a spaceship crashing into the house, aliens escaping from the spaceship etc. Looked cool on video but would you like that across the street every night.
People selling this technology naturally encourage this stuff and like the word classy. But they don't want to think that the word tacky can actually apply. I personally don't respect their opinion.
