Less than a year ago a video put together at a deaf camp racked up more than half a million views in only two weeks. While many videos have been posted on YouTube featuring Pharrell's Happy song, this one featured American Sign Language. Upworthy even said the work of two dozen deaf students was "better than the original." It was filmed at Deaf Film Camp which takes place each summer at upstate New York's Camp Mark Seven. The camp is about to get underway again this year (July 26). You can find out more here and you can read the Deaf Camp's Facebook page here.
