As part of PopSci’s “Future of the Environment” special, we commissioned a modern, eco-themed take on the classic videogame “Frogger.” In our version, called “The Walker,” players have to catch various forms of alternatively fueled vehicles to help them cross a busy highway and make it to school on time. Play the game here—but be warned: once you start, it’s pretty darn hard to stop.
