Relax. There's nothing wrong with your browser. It's just a no-nonsense page for my mostly yes-nonsense experiments.
This is a collection of stuff I've thought about and built at home. At work, I've made grown-up versions of these things for Adobe, Amazon, Capital One, Fitbit, Ford, Google, Intel, Kia, Nokia, Salesforce, Samsung, Sony, Visa, and Wells Fargo.
Most of these don't work on phones or touchscreens (gasp) so dust off your laptop.
