How about this as a way to nudge existing urban design (or lack thereof) with social programming?
GOOD asked industrial design firm Mike and Maaike to take on a near impossible challenge: reinvent San Francisco’s Broadway from a porn mecca that’s virtually empty during the day into a vibrant commercial space. Instead of proposing to tear down down the porn shops and turn the street into a NYC Broadway clone, Mike and Maaike came up with the “Signs of Good Fortune” project, which plants interactive electronic signs into the landscape that generate new fortunes each time they are driven over or stepped on. Instead of trying to overshadow the neon-filled porn shops, the project works alongside them, all while embracing San Francisco’s Barbary Coast gold rush heritage of adventurers seeking their fortunes.
