I had an epiphany today and realized the only thing that I needed to create artificial 3-D simulation was an imaginary z-axis, which would then control size... that's basically how I made this ...ARROW KEYS-- move "Gravity" around. D-- pen down (also generates random color). U-- pen up. C-- clear. A-- move Gravity backwards (away from you). S-- move Gravity forwards (towards you). Have fun!! XD
