Film critic Tommy Edison, who’s been blind since birth, makes a good point at the beginning of this video: Blind people experience the world purely in 3-D, so the thought of converting that 3-D world into a 2-D image on a piece of paper is completely alien to them. This doesn’t stop Edison from giving it the old college try, and so he attempts to draw a cat, a car, and a self portrait. Unsurprisingly, the biggest challenge for him is determining where his pen left off previously, resulting in features that are not proportional or even in the correct place.
