The Mattes are reenacting Beuys' work "7000 Oaks", staging the new performance in the synthetic world of Second Life. The first virtual tree and stone were planted on March the 16th 2007, exactly 25 years after the original oak was planted.
The 7000 basalt stones have been stacked on an island in Second Life. The diminishing pile of virtual stones will indicate the progress of the project, which will go on until all 7000 oaks and stones will be placed. Second Life inhabitants will have the chance to take part to the performance, placing stones and trees in their lands.
