Great website – Animals on the Underground, basically making pictures of animals out of the tube map.
Also, for those that are interested, getting a replacement mirror made by Knaresborough Glass, who seem like a really good organisation – they do made to measure with a 24hr turn-around, and were dead friendly on the phone. Half the price the original one from Wickes too! I guess I should reserve judgement until I see the actual mirror this evening…
