Loki - Location-Based Search and 'Virtual GPS'

Loki pinpoints your exact physical
location and then uses that location to make the web revolve around you,
wherever you are. With Loki you'll always know where you are, make sure that
others know where you are too, never get lost and always be able to find stuff
nearby.

Combining GPS-like location, local search and one-button access to location-based content, Loki is the first web-based application to make the Internet revolve around you. Literally.
