David Gallaugher's grass-lined wheel

FOR
Excellent. Funny. Smart.
It's a brilliantly simple idea. It makes us think - and smile. It is all about ecology. And nature in the city. And taking a real break from all of this. And let's all live together like one happy family.
And above all - don't take it all too seriously. Because it's conceptual - i.e., it is about the concept more than it is about what comes out of its realization. Because it's unpretensious - i.e., it doesn't intend to change the world (at least not the whole world at once). Because it's pretty - i.e., it is a relief from all this...hmmm... down to earth thinking. Oh, and because they got to hear a lot of hamster jokes, apparently.

AGAINST
How do you know where you're going? How long is the grass going to last? So this is the version of nature that architecture students have for us? Don't ask what nature can do for you, but what you can do for nature.

BOTTOM LINE
I like it.
"Even in the Public Gardens [in Halifax, NS], you're not allowed to walk on the grass."
(which is a much better statement than another reported one: that they want to "draw attention to what he considers a North American obsession with manicured lawns.")

ALTERNATIVE

thank you Jan for the link!
UPDATE: The photo of the Grass Wheel is by Andre Forget, a Halifax-based photographer. I'm terribly sorry for not putting the credit before. It is often difficult to execute on the internet (to get to the original source), but it's mainly laziness, and not incapacity or bad will, that is to blame.
