Public toilet hidden from view

The Jinan Environment Sanitation Science Research Centre is working on the first hidden public toilet in China, revealing only its top to curious onlookers. These toilets will able to be installed on lawns along the sidewalk as well as at bus stops and will pop up whenever you drop in a 1 yuan coin. I sure hope these toilets are waterproof in some way or another as heavy rainfall could leave you with a very drenched loo for the unsuspecting!
