press "S" to start creationg press "Space Bar" to reset variables press "R" to do random shapes(mostly looks like a television screen) press "A" to set variables precisely I would realy recommend you to use very little numbers like 0.001 in both variables with "A" so that everything is very percise :) believe me... IT IS WORTH IT!!! also try with big numbers like 100!!! I leave it for you to tinker around to hide variables click "H" to show variables click "G" MY MOST RECOMENDED COMBINATION IS: color(0.001) precition(1)
