Taking an common sight and upgrading it a few notches - the classic street artist, drawing caricature portraits of partaking passers-by. Except now not only people on location would be sketched but also live through the web, be it desktop, tablet or phone.
For this, a live-size mannequin with a "display-face" stood in for the online participants, while a second artist drew the local visitors. All this was live-streamed via several user-sectable cameras, including the artists' tablet screens.
The webspecial, which ran in 3 phases, had people upload their mugshots to be caricatured, and a massive gallery featuring all the participants, both live and online.
The event took place in Hannover, over a weekend, 9 hours per day.
