Hi HN,
When browsing wikipedia, sometimes I find myself asking the question, "when this was happening, what else happened around the same time/location?" After debating whether this was actually useful and researching how it could be implemented, I finally set out to build this tool that allows you to browse and search (almost) all dated events on en.wikipedia. Given an event, it also shows you what was happening closeby, in spacetime.
I don't know how people will use it. I don't even know if anyone will find this useful. But I enjoyed building it.
