DeepDream creator here. Thank you for bringing this up! We saw the huge space for exploration in those simple neural network visualization techniques, and wanted others to share the fun with us. That's why I decided to post it in a form of a notebook, rather than a web-service or a standalone binary.

I think this sub has a potential to become a great place for sharing interesting ideas, but now it is flooded with boring and repetitive dogslugs. There are some beautiful gems here, but they are hard to find. Let’s try not to loose them.
