“Not everything hidden is meant to be found. But if you’re here... maybe you were meant to see it.”
H4J4R4.2 is a small experiment I built using pure HTML, CSS, and JavaScript.
It simulates a cyber-terminal interface — complete with matrix rain, fake access prompts, decryption sequences, and an internal file system.
It’s basically a fun, interactive “terminal illusion” that runs entirely in your browser — no frameworks, no servers, no APIs.
I made this just for fun for a friend. I just wanted to see how far I could go building something that feels alive using nothing but vanilla web code.
Now it’s here — weird, geeky, and kind of awesome.
