I discovered a really interesting web application this morning during my procrastination time: meetmidway. The application allows you to chose two geographical points and an activity (such as a movie theater or coffee meeting) and it plots the course, the midway point and the nearest place for that activity to the midway point.
It uses google maps to run the query, although it is running off the web right now the founder has expressed interest in building a mobile app (which would be much more useful). I wonder if the mobile app will be a GIS M.Sc. project...
Fun, if you like that sort of (geography) thing.
