Frankly I have no idea why are people acting so impressed. ~15 years ago were extremely common images which showed user's IP address, it was usually done in PHP using imagemagicks. This is basically same, just with added cache of text which is then showed. I even remember POC html/server only chat which sent clients new gif frames as they posted new messages (found it [0], it's over 20 years old). That was much more impressive.
