Hmm, inspired stuff. Especially the first one that looks a tad Burning Man. I'd be interested in knowing how practical they are from a parking/safety POV.
On a slight tangent, who uses the organic-style parking loops on High Street Westgarth? (trendy name for South Northcote) They were installed in the late 90's, I was wondering what people thought of them. Practical? Inpractical?
