Food safety ratings when you checkin on Foursquare
It uses the FSA’s open data API and attempts to match them to places on Foursquare, then uses the Pushover app for iphone and android to tell you the rating.
More work is needed to improve the matching of places between Foursquare and the FSA API (due to differences in names - like ‘Ltd’ and differences in coverage). So no guarantee you will get an alert, but it seems to work quite well.

Wikicity125 finds nearby Wikipedia articles as you travel through the landscape. You can read them as you trundle along, or save them to Instapaper for later.
New articles are automatically added to the top of the screen as you get nearby, then gradually fade out as you move away. No maps, no pins, no searching.
There are plenty of games and apps that make use of location to collect, check-in to or find things in the real world. They use GPS and geoIP to work out your location.
But what if you wanted to build something on The Tube (London’s underground transit system)? An app that let you collect tube stations, told you their history or even a real life version of Mornington Crescent? No GPS, no geoIP.
If there is a one-to-one mapping between tube stations and the IP address you get assigned when connected to the network then it would be possible build apps that knew your location underground.
So I’ve built a mobile web app to try and build a geoIP database of the underground. Bookmark it on your phone, and next time you are commuting you can help map the tube. In return for mapping a Tube station, you get a factoid about it.
The data everyone collects will be available here.
Note: this might not work, and yes, it is all a bit silly.
Edit (Dec 2012): It seems this isn’t possible. The IP addresses don’t seem to be fixed to stations in any reliable way.
