Teaching Machines to Draw
I've read through all comments and referred docs, but no one seemed to offer much reason why we'd want machines to draw sketches. An incomplete list:<p><pre><code>  * It's a different way to represent drawings. Alternative to pixels  
  * Perhaps making it easier to render old-school animation at one point?  
</code></pre>
It's a fun rabbit hole though, the many sub-perfect bicycle sketches reminded me to this project, when someone created 3D renders from bicycle sketches: <a href="https://www.behance.net/gallery/35437979/Velocipedia?ilo0=1" rel="nofollow">https://www.behance.net/gallery/35437979/Velocipedia?ilo0=1</a>
