I am confused? How is this being upvoted? This kind of project has been a staple in the programming community from gaming to forums for two decades now.
And instead of being snarky, you could actually explain what is so novel about dynamic image generation on a server.
This is generating a custom GIF file on the server. It's most likely been done by someone somewhere before, but not something I've been both gaming and forum-ing for a little while.
The watch on the home-page displayed the current time with moving hands that were behind reflective glass. It was a server rendered gif. (c) 1996 or '97.

I have not seen a generated GIF before.
