Foursquare Hackathon's 3 Gems: A Profile Pic Automator, Divorce Counter, And Toilet GPS Inspired By Seinfeld

From Paris to New York, Tokyo to San Francisco, developers from around the world turned out for Foursquare's global hackathon this past weekend. The aim? Like any good hackathon, to seed innovations in a round-the-clock binge of hacking and 5-Hour Energy.

By the time Fast Company arrived to New York's gathering at General Assembly, many of the bleary-eyed devs had already moved on from 5-Hour Energy to Sixpoint beer (basically a deconstructed Four Loko) in celebration of all they had accomplished in such a short span. Here are three of the creations we found particularly fun and interesting.

PlaceFace

Profile pictures have long been too static--typically vain self-representations of ourselves that we change rarely or randomly at best. But Jason Pope and Jonathan Wegener, the brain behind the popular 4SquareAnd7YearsAgo hack, has created PlaceFace, an app that lets users change their profile pictures automatically to reflect what they're currently doing. So rather than having a single profile pic, users can now choose a slew of photos that will update depending on your Foursquare status. Check in at a nightlife spot, for example? Your profile image might change to a picture of you chugging wine. Or check in to a library? Maybe a picture of you reading. And so forth.

It's a fun twist on the age-old profile picture, updated for Foursquare audiences and all the places they frequent (shopping, A&E, food, offices & buildings, parks & outdoor, travel).

How [Blank] Are You?

Created by Max Stoller and Tal Safran, How [Blank] Are You? is a service that crosses Foursquare check-ins with 2010 census data to give a sense of the demographics of the neighborhoods you most often hang out in. The service is broken down by a few intentionally simplified metrics (gender, marital status, race) to answer one question: How [blank] are you? That is, how white are you? How female are you? Or how single are you? For example, if you check in to 10014 (Manhattan's West Village) or 11211 (Williamsburg, Brooklyn), the service might say you're 80% white, meaning you often bounce around to predominantly Caucasian neighborhoods.

When plugging in his own data, the service concluded that Stoller was 10% divorced. "That's about right," he joked.

Loo Review

Remember George Costanza's app from the Seinfeld reunion meta-featured onCurb Your Enthusiasm? Called the iToilet, Georgie Boy's fictional service was designed to help iPhone users locate the nearest "acceptable" public bathroom via GPS. Now Jon Gottfried, developer evangelist at Twilio, has turned that fiction into a reality with Loo Review, an app that does exactly as its name suggests: a Yelp for restrooms. By pulling in Foursquare location data, Gottfried has enabled users to snap photos of bathrooms, tie them to check-ins, and have the app "scan" the image to rate the cleanliness of facilities.

His central finding? Don't use the W.C. at the Equinox in midtown.

    I just got a $829.99 iPad2 for only $103.37 and my mom got a $1499.99 HDTV for only $251.92, they are both coming with USPS tomorrow. I would be an idiot to ever pay full retail prices at places like Walmart or Bestbuy. I sold a 37" HDTV to my boss for $600 that I only paid $78.24 for. I use (Bidsget) . (com)

    Also, for the Harry Potter fans out there, check out http://muggleclock.com. Displays friends recent checkins on a clock similar to the "Weasleys'
    family clock" found in the "Harry Potter" book series. The hands
    automagically move as your friends checkin to different venues.

    God me too! I'll sign up! Italy -surprising pristine toilets everywhere on last visit, Paris, absolutely dire and Geneva -shocking,it took a series of public toilets here, all using low,blue light for me to discover it's used, so that addicts have more difficulty locating their veins to shoot up:-( why the hell can't we have access to free,clean public toilets? That includes airports- Berlin Schonefeld I'm especially looking at you!

    loved the hackathon at #tcdisrupt but you just cannot beat the loo review!  That would have saved me quite a few times in Spain!  Sign me up!
