Publicity whore
The Eden Project, one of Cornwall's biggest tourist attractions, has an education centre with a wall made up entirely of refridgerator doors. If there's a teaching purpose to it, I missed it – as far as I could see it existed mainly to give people the chance to play with the hundreds of letter-shaped fridge magnets on it.
I couldn't resist the opportunity to promote my website address – as high up the wall as I could reach so it would stay there and not be broken up by other people searching for those hard-to-find “Ws”.
