I've always had a hard time visualising the passage of time when viewing my GPX tracks. I wanted a better way to relive the moment and stimulate memories of what the day was like, so I put together this little visualisation that works with any .gpx track[1].

[1] .gpx track must have timestamps

If you don't have a .gpx track, you can also explore a world wide interactive map displaying terrain shadows throughout the year: https://shademap.app
