This image was rendered by Alexander Mordvintsev on 18 May 2021, the 6th anniversary of the DeepDream creation. The starting image and the neural network match those that were used for the creation of the first DeepDream images. The code that drives the generation process is itself an artistic experiment. It’s called “deepdream.c” and is built using the set of technologies that were already available more than 30 years ago, but still widely and actively used today at the basis of our software infrastructure. The code relies on C89 standard and the minimal set of language library features. It’s designed to be as self-contained and easy to build as the “Hello, World!” program. The artist hopes that this kind of software would be possible to build and run long after his physical death.
