Silly -- Xmas is a celebration of the consumer ethic and perhaps also inspired by a human desire to mark midwinter, this was the most important date in the Pagan calender and probably has much more to do with our annual orgy of consumption than Coca-Cola's father Xmas or some homeless couple with a baby , it really is a shame the whole thing has been hijacked by religous fundamentalists with a phobia about red nosed mammels, perhaps...
Here is a siily Xmas films I did. No keying as was done on a whim and had to make do with some dodgy masking.
