I love the use of color and the retro-style UI. Your INSTRUCTIONS.md was comprehensive.

Appears to be CPU-heavy sometimes in the browser (spiked one of my CPUs to 100%), so could be an opportunity for optimization later.

I've often wanted to show my clients how risky their brand-new VPS is without proper firewall configuration. Your Knock-Knock tool would be a great way of helping them visualize that.

Very nice app; great job!

The goal is to educate people (originally my kids) about one particular aspect of cybersecurity. I love it when people use the site for this purpose.

Yep, with ~80 knocks coming in per second and two 3D globe visualizations, it does make a lot of use of the browser. That said, it runs smoothly even on an iPhone browser. The server scales really well (longtime load average of 0.05 on a $6.75/year VPS :-).

Thanks!
