IDK why this is being downvoted, it was indeed published two year ago, they just apparently repackaged this as an easier-to-use tool:

Before there was a dense scientific paper. Now they've released an incredibly simple tool that lets anyone draw photorealistic images with simple strokes.
Saying that is repackaging something into an easier-to-use tool seems like quite a stretch. They didn't put a GUI on curl or something.
