If you ever lose faith in humanity's capacity for creativity and talent, just remember there are people like Chan Hwee Chong in the world. He was commissioned by Faber Castell to recreate famous paintings, and boy did he ever. Each of these portraits is created using just a single line that spirals outwards from the center. Amazing!

Just when you thought you've seen every method for creating paintings, another Amy Shackleton comes along. Amy creates these psychodelic paintings without a paintbrush.The great lines and forms of her paintings are created by applying paint with squeeze bottles, and allowing gravity to do the work. Check out the video below for a cool demonstration.
