Wow, this is awesome. Glad to see the developers hard at work – the hackathon is a brilliant concept and never ceases to amaze me at the wealth of ideas that come out of it.. amazing what a couple of geeks fueled up on coffee, pizza, and redbull can do! Last week’s round-the-clock, round-the-world global hackathon saw more than 500 developers all over the globe produce a ton of incredible apps built on top of the foursquare API – about 90 developers were recognized.

Details of some of the finalists and crowd faves:

• Sqavenger to create or play a scavenger hunt via text message and foursquare
• Intersquares (by Mihai Parparita in SF) lets you see the intersection of your foursquare check-ins with a friend’s.
• Near.co for building the best website using our new venue Push API. A four person team in SF worked through the weekend to build a digital screen replacement so that store managers can usher in the modern storefront with foursquare
• VenueMachine, which allows venue owners to identify and reward influential visitors in real-time.
