Ancient mars i: the sephine age was generated by the visual evolution engine (VEE) from a NASA image, composed of photos taken by their Martian dog. The evolution takes the original back billions of years, to a time when there was water on Mars. (The figures and the Martian home were evolved and overlayed separately.) Here is the original NASA image:
VEE does not employ standard Artificial Intelligence techniques to mimic existing art, but it has a mind of its own. As well as adding the greenery etc, it decided to rearrange the mountain ranges on the horizon, and alter the perspective.
The figures were created with VEE and ALISA, Adaptive Layered Image Synthesis. The OpenSea NFT is here, a single token to purchase a single artwork. The token includes unlockable content consisting of a high-quality digital image (not available on-line) suitable for printing and framing.
