* Time Span: 4,000,000 BCE to 1993 CE
* Mobile-Friendly: presented as a stack of cards on mobile devices for easy finger-browsing
* Card View: whether viewed on desktop or mobile, each information card is uniform sized, with consistent illustrations and a concise summary of a historical event.
* Timeline View: on desktop devices, you can temporarily hide the cards to view a networked timeline of historical invention milestones directly (you can zoom in/out to have better view)
* Hightly Open Source: all data --- including card information and networked timeline data --- is stored in a publicly accessible Google Spreadheet, accompanied by a GitHub repository containing the executable code used to generate this website (though I have not tested it myself)
