Hey, check it out! It's a literal random walk generator fit to tweet-a-program!
Grid@{{DynamicGeoGraphics@#}, {#[[2, 1]]@"ManeuverGrid"}} &@{#,
GeoPath@TravelDirections@{Here, RandomGeoPosition@#}} &@GeoDisk[]
I made the heart of this for the One-Liner competition at the Wolfram Technology Conference, but it didn't hit well, so I improved it to this. Can anyone improve it further, while still keeping it under 128 characters? I wasted some on the Dynamic, sure, but.....it adds something the other one was missing at 79 characters...character(s)!
