Geo Location Atlas
Once visited, you can see nice OVI map of place based on ISP of yours with clickable foursquare places to explore. Plus current weather and forecast displayed. Just below the map you can see latest tweets from location (refresh tweets works too as well as located news feed). Little magic thing happens when a place name (or address/city) entered instead of detected IP. For example Sherlock Holmes Museum - to see what's up at Baker Street -> OK. Know the place and want to refresh memories? Or wanna check views of where never was before? Look, geo photos from flickr and instagram are on the right... Click for the picture full details or browse for next. Previous tweets from specified location (as far as available) are reachable. These tweets location radius is adjustable as well (to investigate the exact place or wider range). One more cool feature is you can refine tweets within that radius for specific search words. For instance, to locate tweets with photos from these geotagged scope just enter word (at bottom left) photo -> click search within! Well, links on these photos (usually from fb, instagram, twitter, tumblr and others) are clickable... Hm... looking for ... what if to enter instagram cats -> search within? What are (they tweeting about) recent news in newspapers ... ok, let's check nytimes -> search within! More results? Just click Radius+ to increase search area... Still using google search? Better use (twitter geo powered) search within! BTW, how about twitter videos from the place? Sure, click THE VINES to watch it playlisted... API for vines: (unofficial yet). Under tweets feel free to check what's top on Amazon by random category (at the moment from 10 available global locations)! And below that are random space cats pics (for your pleasure)..

HangoutLater HangoutLater
Foursquare is awesome for meeting up with friends - it notifies you when a friend checks in close by so that you can go meet them. But, sometimes a friend checks in while you're busy - at dinner, seeing a movie, etc. You want to hang out with them when you're free, but you won't unless you put in a lot of effort into co-ordinating plans for later. That's where HangoutLater comes in. When you checkin somewhere, HangoutLater notifies you on Foursquare that one or more of your friends have checked in close by recently. It then suggests a fun place between all of you where you guys can meet up when you're free.

Fourpocalypse Now Fourpocalypse Now
One of the most popular things to come out of Foursquare is the idea of a something-pocalypse, that is, a catastrophically popular event local to a particular area that thousands of people check-in to. They pop up all the time, but you might not know it, so I created a tool to find foursquare apocalypses happening around a given location with help from the Foursquare and Google Maps APIs.

A simple social update will do. And the social scope of this service doesn’t stop at that. No, WhileWairport lets you meet up with people who are in the same airport that you find yourself in. You can look for people who share your same hobbies and interests, and have a much more pleasant wait if your flight’s been delayed.
