The Artvertiser is a software platform that replaces billboard advertisements with art in real-time. It works by teaching computers to recognize individual advertisements so they can be easily replaced with alternative content, like images and video. 
A user must hold special Artvertiser goggles up to an advertisement to see artwork appear as a superimposed layer of augmented reality (or "improved reality," as creators Julian Oliver and Damian Stewart prefer). The software is open-source, and anyone is invited to download the code and contribute to the project. Oliver and Stewart are currently developing Artvertiser apps for Android, iPhone, and Nokia N900, which would let more people enjoy Artvertisements, but sacrifice the high-quality immersive experience of peering through the special goggles. The project has been shown in Berlin, Brussels, Rotterdam, Madrid, and Helsinki.
