I'd like some way of people to temporarily stake their claim on the parklands.
Everyone who bids can select a 1 metre square patch of turf. Their favourite place. They can mark it on a map, explain why. Even for a day or a weekend or an hour they can mark their territory in some way, low impact, no waste, etc.
sort of like the Occupy movement. Occupy the imagination. Imagine this is your parkland. What would you like around you? What's missing? What's abundant? Just a way to engage.
