Love NZ - It's a Karma Thing
We wanted to encourage Kiwis to recycle, so we gave them some good Karma. You do good, you get good. Our 'It's a Karma Thing' App allowed Kiwis to bid on items using Karma Kredits they earnt from recycling. Basically we built an eBay, got it to sync with real world bins, as well as allowing users to easily find their closest bin, encouraging even more recycling.
