This is essentially like a 3D JPEG, but instead of modelling the image with Discrete Cosine Transform (DCT) they use a neural net. So the neural net itself will learn just that one image and be able to reproduce it point by point, from various angles. A whole network for just one example, and an innovative way to look at what a neural network can be.
