I produced something similar to this shortly after the release of https://github.com/karpathy/char-rnn:

Basically, you create a video, dump the video's frames with ffmpeg, run each frame through the RNN, and stitch them back together. It took me several hours to produce just ten seconds of video. Unfortunately, unless you have a Titan X GPU the max size of each image is quite small (certainly less than 1080p), which may be why the frames in this video are split into four quadrants.
