When fruit flies die, they don't go to heaven, but they do get to go to outer space. At least that's the conceit of artist HsienYu Cheng's Collector: Afterlife, which zaps bugs with high voltage and then reincarnates them in a Space Invaders-style video game. Each dead fly translates to one extra life for the onscreen hero. When the lives run out, the player has to wait around for more flies to wander into the trap's deadly blue light. It's a digital age update on the concept of rebirth, or just a new take on the spider and its web.
