A mobile website that checks whether you're in the former East or in the former West Berlin.
Some friends and I were having a barbecue at Tempelhofer Feld – a huge green area in Berlin – and I asked naively: hey, was this the former East or former West Berlin? One of my friends instantly claimed to know the answer - 'West, of course!'. But we had no way to check.
That's why I created west-or-east-berlin.com. It's a mobile website that shows you whether you're in the former west or east of the Berlin wall. In order to decide that, of course, you will have to allow access to your current location in your mobile browser.
