Have a look at this strange construction. Is it a new fashionable toy for the urban citizen, lacking nature, a new method of generating green energy or a demonstration to protest against experiments on animals in cosmetic factories?

Not at all, this is a creation designed in 2006 by a group of students from Dalhousie School of Architecture in Halifax, Canada. The students found this funny way to protest against the lack of green spaces in their city.

This hamster grass wheel for humans is indeed a good provocation to ask for more green spaces, but can also evoke interesting questions about our lack of time to enjoy them. Should we all be carrying a piece of grass with us to take profit of it? This may be needed in our modern cities where concrete, cars and speed are three fundamental ingredients of its grey alchemy.
