Draw This is a practically nonsensical, but experimental yet very impressive (art) project. It is a kind of instant camera that outputs a line drawing of the recorded subject instead of a photo. Or just what the camera thinks it recognizes on the subject.
The technology behind it is neither fresh nor particularly complex for current AI conditions. With a Raspberry Pi and a thermal printer you can even build your own "Draw This" camera due to the open source nature of the project.
The principle of the camera is based on millions of scribbles, which Google collects through a kind of 
online Monday Painter App and makes available free of charge for AI projects. Subsequently, a tensorflow model was trained to assign these labelled drawings to patterns in real images. The trained model is small enough to run on a Raspberyy Pi.
So "just" a funny gimmick, which still clearly shows how much is already possible with common AI tools and inexpensive hardware.
