Would you want to live in a world that looks like a Pandora knockoff, or blares like the wall decorations of a stoner crash pad? What if you couldn’t turn it off?
Such were the questions raised when a Kickstarter campaign launched to “create real glowing plants in a do-it-yourself biolab in California.” At first, observers merely wondered if the technology could work.
