Urban Alphabets (currently for iOS and Android platforms) encourages users to re-experience their surroundings by enabling them to utilize their smartphones to upload photographs of individual, cropped letters, which can then be used to write short messages, called Urban Postcards. 

This project consists of many different parts (smartphone app, website, urban screens, workshops). Here I show the webdesign and implementation, which you can see live at: www.ualphabets.com 

Technically the implemetation consists of HTML, Javascript (few JS libraries) and CSS. I also implemented the back-end myself, done in PHP.
