Bad decision, dumb idea, humiliating memory?  Suffer no more from the merciless irreversibility of error!  Images and Charles Street's annual commissioned video program hits Command Z: the keyboard shortcut to "undo".  With the magic of digital technology enabling all failures, sinners and screw-ups to apply a transcendent Delete Key to the typos of life, five artists respond with short videos motivated by the universal urge to cancel, forget, erase or just make it go away. See descriptions of Command Z artists and their works under programmes on right hand side of this page. This time, don't blow it.
