This is a super-cool project. GANs are extremely interesting to experiment with in a creative manner. One thing I often miss in these websites, however, is what I think is one of the most interesting aspects of GAN visualization - namely, a video feature for showing latent interpolations. I guess this is often skipped because inference is done server-side and there's (naturally) limits enforced to avoid excessive use of resources.
In that vein, I've created a webapp [1] that runs entirely client-side using TensorFlow.js, and let's you generate videos of latent interpolation, images and tweak with parameters using a less-conventional generator trained on many different datasets.
