The lights ident on C4 is easily my favourite Christmas ident of recent years, but just like with Oneness I feel like C4's Christmas presentation shows up how poor their idents are the rest of the year.
Had C4 continued with their original mini-blocks concept for the idents I think they'd have been potential for some really nice Christmas idents using that - i.e. a tree made out of lots of miniature blocks, kind of similar to the previous Sky idents.
It's great that everybody gets sarcasm.
