Seems like every Christmas there are more and more opportunities to spend your money on yummy graphics.

Coming up in just a week's time, Pictures on Walls' Santa's Ghetto opens its doors once again, selling a selection of limited edition prints by Banksy and friends. Though with Banksy's recent transition from underground spraypainter to overground art-commodity, it'll be interesting to see if he's still playing with the other kids...

No word yet on the location of the store - last year it squatted on Oxford Street, which meant big queues, and didn't feel quite right. Or perhaps felt perfect. We couldn't make up our minds. Anyway, stay tuned for more news as and when. UPDATE: See here.

If that's all a bit street for you, then you can head over to the more genteel surroundings of Somerset House for the Design Grotto, where designers and illustrators will be offering all manner of festive goodness, including a limited edition set of Christmas postcards in aid of the Rainbow Children's Trust. We're guessing it will be a bit like the V&A Summer Fete. But inside. At Christmas. It runs on Saturday 15 December (6pm - 11pm) and Sunday 16 December (11am - 6pm), in the Portico Rooms.
