    Running Reality

    Running Reality

    World history plays out down to street level on a detailed map.

    Running Reality no longer uses SourceForge. Visit us at our homepage! We at Running Reality believe that we can use the power of today's computers and mobile devices to bring history to life in an accessible, immersive, and engaging way for K-12 students, history enthusiasts, and visitors to historical sites. Running Reality gives you a map that lets you go any place on any date from 3000BC to today and explore down to the street-level of history. This model has nations and cities but also ships, armies, buildings, and people. Towns grow, buildings are constructed, ships explore new seas, and armies battle. Harbors silt in, rivers change course, and cities are sacked and burned. When you are standing at a historical site and using your mobile phone, you can see all the events that happened around you at that exact spot then zoom out to see the context of what was happening more globally.
