check out these wonderfully imaginative playgrounds by Monstrum. the following is from their website:MONSTRUM believes that playground design should be a reflection of the world surrounding us. We see the world as a place full of colour. We meet boys that like pink and girls that likes trees, so why only play on a monky frame and a sandbox, when you can play in a moon crater or a submarine or a giant spider or an enormous snail or a Trojans horse or a rocket or an ant or a princess castle. The fantasy is infinite.
