Folks keep thinking that the link sharing with Twitter and FB are broken because the image is so pixelated. It is pixelated on purpose. I agree that it looks especially janky on FB.
The blurry image allows distribution without having to get permissions from those in the picture. The blurry image also used less data. Learn Improv is used all over the world by folks with varying levels of intertubes access. Less data means more improv.
The picture contains the blurred images of many of the people that Learn Improv was tested on around 2007. They also look happy. Blurry and happy.
