What is the most interesting website you've ever visited?
Many put Neal.fun at the top — it hosts dozens of interactive experiments. Library of Babel is hard to beat philosophically: it contains every book ever written or yet to be written.

The best cool websites have a clear creative vision — they exist because someone wanted to make something genuinely remarkable, not just useful.
