Show HN: An interactive map of Tolkien's Middle-earth

An interactive map of Tolkien’s Middle-earth, with events from across the legendarium plotted as markers.

I have been commuting a fair bit between the East and West coast, and thanks to American Airlines' free onboard WiFi, I was able to vibe-code a full interactive map of Middle-earth right from my economy seat at the back of the bus.

It's rather amazing how much an LLM knows about Tolkien's work, and it was fun to delve into many of the nooks and crannies of Tolkien's lore.

Some features: - Plot on the map the journey of the main characters in both The Hobbit and The Lord of the Rings. - Follow a list of events in the chronological Timeline - Zoom in on the high-def map and explore many of the off-the-main-plotline places - Use the 'measure distances' feature to see how far apart things are.

I also had a lot of fun learning about tiling to allow for efficient zooming.

If you are anything like me, this should provide a fun companion to reading the books or watching the movies (note that on this site, I followed the book narrative, and did not include Peter Jackson's many departures)

If you get the chance to check it out, I would love more feedback, and if there is demand, I might do the same for Game of Thrones.
