An experimental tool by Shaobo Guan generates realistic photos of people. You can alter gender, age, race, and some facial details. StyleGAN from Nvidia is one of many similar tools. There's even "Hot or Not"!

An algorithm by Tom White draws abstract illustrations of real world objects. It's trained on photos and the result is close to usable in real products. It's a part of Google Artists and Machine Learning initiative (read its blog).

This bot generates images from caption-like text descriptions. It can be everything from ordinary pastoral scenes, such as grazing livestock, to the absurd, such as a floating double-decker bus.

The product team added buildings and areas of interest even for smallest cities using satellite and street views photos. Their 3D models are so detailed that you can sometimes see the blades inside the rooftop fans. Looks like Apple does it manually.

The mobile app transforms videos into single-page comic layouts. It automatically selects interesting video frames, lays them out, and applies one of six visual styles.

Cambridge Consultants made a tool for illustrators that transforms rough sketches into a painting from Van Gogh, Cézanne, or Picasso.

Researchers from UC Berkeley converts impressionist paintings into a more realistic photo style.

A plugin generates modern confetti patterns that fit into existing screen mockup.

An experimental projects turns sketches into icons. It can help non-designers to use quality icons in their mockups. Researches turned it other way around — algorithms makes human-like sketches.

The app can process video through neural networks (even streaming video).
