It's just a page with a lot of small images (all directly loaded from the repo) and a short description for each. After loading half of the images GitHub throttled me and blocked requests with an error message about abuse.

After 2 minutes I was able to access GitHub again but I imagine they will block you for longer if you try to do it again and again.
