I would just like to point out that anyone who objects to these things on their aesthetic merits is hypocrite of the highest order. Christmas decorations have always been about the gauche intersection of consumerism and neighborly spectacle; to claim that laser projections are somehow objectively more of an eyesore is missing a bedazzled forest for a single fake plastic tree.
The only intellectually consistent positions are to embrace the entire spectrum of ostentatious crap we do to our homes in the name of being “festive” or to denounce all of it for what it is.
But this is a stupid point at which one should draw the line.
