Vimscript: How to URL Encode a StringJanuary 25, 2017

Draw Giraffe, See a MovieOctober 8, 2016
It struck me today as I was drawing giraffes with 4 year old Hazel that within a few years it should be possible for a child to draw an animal, whether it be a giraffe or a dog, and have the computer use that as a style blueprint.
It should then be able to take the pre-rendered model for a short movie involving that animal and use the stylized version of the animal when rendering a new cut of that movie.
It might also be possible for the child to give some direction about what should happen in the movie, such as the giraffe running from a lion and then escaping by jumping over a river, and have the movie include those components.
How far away are we from that? Could a compelling prototype be built within 10 years perhaps?
