Dispatchwork is project by Jan Vormann where he fills up holes in walls with Lego bricks. He did this before in Bocchignano, a village close to Rome, and Tel Aviv. This time he did in Berlin, where he and many spontaneous helpers filled World War II bullet holes at a building of Humbold University. You can find some other patched walls around town too.
He also has a exhibition at the Jarmuschek + Partner gallery in Berlin till June 13th
