There are screws all around us—in fact hundreds and thousands of them! This is what makes Japanese designer Yuma Kano’s participatory art project so brilliant.

In short, the "screw :) project" is an initiative to swap out regular screws all around the world for smiley-faced ones, and plot them on a map so others can find them. Together with Komuro Seisakusho, a screw factory in East Osaka, Kano has made the screws and screwdrivers commercially available, and for each screw sold one dose of polio vaccine will be given to a child in need through JCV, the Japan Committee, Vaccines for the World's Children.
