TimeBomb is the brainchild of digital artist Lukasz Karluk (Holler) and Sydney sculptor/painter Maddi Boyd (KissKiss). Merging interactive programming and traditional wild-style graffiti painting (“bombing”), Time Bomb allows the audience to unlock the secret history behind a graffiti wall. Over four days nine urban artists contributed to the TimeBomb piece: DMOTE, Ben Frost, Kid Zoom, Numskull, Roach, Creon, John Doe, Bennett and KissKiss. Painting layers upon layers of different styles, their work was documented through time-lapse photography, creating an animated film of the whole process. The final installation will feature two giant graffiti walls suspended in the museum. One wall will be the real painting, the other a projected film double. The visitors' physical movements in the museum can then control this film, going backwards in time, revealing the now-covered layers of graffiti.
