an event for hackers whose medium is art and artists whose medium is tech. A typical Art Hack Day event brings together 60 artist-hackers and hacker-artists to collaborate on new works in a hackathon-style sprint of 48 hours leading up to a public exhibition and party. The artworks often demonstrate the expressive power of new technology, radical collaboration in art or a critical look at how technology affects society. The technology used is typically open, and sharing source code online is encouraged.
