From the group that brought you the Healthy Penis - the six-foot-tall costumed character that appears at street festivals around town - comes a very adult iPhone app. Called STD411, it is aimed at gay, bisexual and transgendered men and features a “player’s activity grid” showing how likely it is that a particular sexual behavior will result in a particular disease. A green condom means go for it, a yellow condom means be careful and a red condom means steer clear.
