Video game art is a specialized form of computer art employing video games as the artistic medium. Video game art often involves the use of patched or modified video games or the repurposing of existing games or game structures, however it relies on a broader range of artistic techniques and outcomes than artistic modification and it may also include painting, sculpture, appropriation, in-game intervention and performance, sampling, etc. It may also include the creation of art games either from scratch or by modifying existing games. Notable examples of video game art include Cory Arcangel's "Super Mario Clouds" and "I Shot Andy Warhol," Joseph Delappe's projects including "Dead in Iraq" and the "Salt Satyagraha Online: Gandhi's March to Dandi in Second Life," the 2004-2005 Rhizome Commissions "relating to the theme of games," Paolo Pedercini's Molleindustria games such as "Unmanned" and "Every Day the Same Dream", and Ian Bogost's "Cowclicker."
