We're big fans of innovative gameplay here at PopSci, and the web browser can provide the perfect, simple canvas for that. For example: You may be familiar with the game QWOP, created by Oxford professor Bennett Foddy, whom we featured in our PopSci Arcade earlier this year. In QWOP, you frustratingly try to direct a person through a race by moving their limbs using the Q-W-O-P keys. It's almost impossible to beat and almost impossible to put down. Now, from the same productivity vampire comes CLOP. This time you're a unicorn.
