I recently came across Numen's creative interactive installations, a mix between art and design, on the landscape architecture blog Landezine. These are the same guys who strung up an alien-like web of packing tape in Melbourne's Federation Square last year. Their most recent project, Net, is a series of flexible nets suspended in the air, connected at various points to create an undulating and disorienting landscape. Or, as the designers call it, a "community hammock."
It was installed at the House for Contemporary Art in Hasselt, Belgium, last summer. You can watch people interact with the installation here:
And also here:
I love their creative, unexpected use of everyday materials, and I'm eager to see what they'll come up with next!
