The 'Parkwheel' by David Gallaugher is a grassy cylinder that you can walk in. Gallaugher is an architect who graduated from Dalhousie University in Halifax, Nova Scotia. Almost like a hamster wheel, with every step the wheel turns a bit more. You can now walk the city shoeless and feel the comfort of grass under your feet.
The Parkwheel by David Gallaugher is the never-ending lawn of your dreams. Don't try to take your lawnmower to this bad boy. I don't see that ending well!
