I can't offer any of my own until Christmas - we keep the twelve days - but there are some striking examples of tackiness appearing already - including some decorated rubbish ships outside a hire place which rather stick in the memory as totally naff.

I will power up the camera to suitably record the Days of Tacky Twinkling.

Maybe you could make or otherwise obtain a Christmas cake? Nothing like trying to feel sorry for yourself on Christmas day afternoon with the cake, nuts, cheese, a few apples, perhaps, and a glass or three of port/brandy/whisky/whiskey/rum/drink of choice, with a recording of Christmas music playing or some old film with a suitably seasonal theme on the telly.
