I highly recommend artbreeder (formerly known as ganbreeder). It is a website that uses deepdream neural networks to create images. Unlike style transfer which is cool but unless used in subversive ways just copies other art, artbreeder allows you to create totally new images from realistic to totally abstract or disturbingly in between.
It really feels creative and is the neural network equivalent of walking along a beach and collecting seashells you like.
