Basically a Java algorithm interprets a PNG into ASCII (represents each cluster of pixels as an appropriate character) and saves it. This interlaces with some Google Maps APIs and allows you to interact with a retro Google Maps page all rendered in ASCII, still with location searching and all. A Go web server handles all of the IO and stores photos that users upload at given locations, which other viewers can see. These photos are, of course, rendered in ASCII. This is a very inspirational project and has infinite potential to change the world. Or at least, to bedazzle the eyes.
Note that all text is rendered in black and white, and therefore the stupendous color in some images is an optical illusion.
