The first thing they noticed was the ears. They were just plain wrong. They seemed tiny--really, really tiny--when they were supposed to be big and pointy. That would be strike one against him: the absence of that universal trademark, his Vulcan ears. And what was he doing with that scruffy beard?

It's increasingly common to use artificial intelligence (AI) in art. Google has popularized this process with its platform, Deep Dream Generator. What began as a way to help engineers and scientists understand artificial neural networks, a form of AI, has blossomed as a means to create art, producing images that have been described as "trippy" and "psychedelic." Outside of Deep Dream, artists are using other forms of AI to produce portraits, landscapes and abstract works of art. AI has made significant strides since the 1950s, when it became established as a field.
