Coder Art Mode is self explanatory, and quite complex to activate: 1) Navigate to the Trophy Screen 2) Tap Triangle Button once on the top left hand corner trophy. 3) Scroll down to the bottom left hand trophy (trophy 136) and tap Triangle Button twice. 4) Then go to bottom right hand corner trophy and tap Triangle Button 3 times. 5) Then to top left hand corner and tap Triangle Button 4 times. 6) Then back to trophy 1 and tap Triangle Button 5 times - and so on until you have finished on the top right hand trophy and 8 taps of the Triangle Button.
