a visualization tool that is able to generate a wireless (WiFi, 802.11) heatmap based on signal strength. an obvious application is to find the best physical place or area to work wirelessly with the highest signal strength. the tool allocates a 2D grid that overlaps the geographical sample area, working out the average signal strength based on nearby sample points.

This should be rewritten for GPS-enabled smartphones (iPhone, etc) to grab the location automatically, and could then even run in the background and give you hints when you lose your signal strength such as: Move northwest to get a better signal. Anybody seen this done?
