From selfies to virtual reality, how technology is changing the art world

(CNN)In 2002, a self-taught programmer named Cory Arcangel hacked the code of a Nintendo Super Mario cartridge, stripping away all the graphics except for the fluffy pixelated clouds.

Two years later, his artwork “Super Mario Clouds v2k3” made Arcangel one of the 2004 Whitney Biennial’s breakthrough stars. Yet many of his new fans, Arcangel once told me, did not really understand what he had done: they thought they were watching a digital video, not hacked software.
