Last year, PETA issued a Groundhog Day challenge, and students at Pennsylvania's Lafayette College responded to it by inventing a robot that can detect shadows. The students plan to unveil their creation this week.
We think that using a cyber shadow-detector is a great alternative to yanking a frightened groundhog out of a fake burrow every February and waving him around in front of a boisterous crowd as cameras flash in his eyes. Groundhogs avoid human contact and spend their days digging and burrowing. In February, they should be midway through their winter hibernation, not dodging the paparazzi.
