Tonight I ported the code from Processing to an Arduino. The test installation here is a 5 meter stripe with 100 pixels in total. So besides from removing any "println" commands and changing the definition of every array I spent quite some time with re-defining the positions of most of my objects since most of the coordinates were given in absolute numbers and not relative to screen size.

Most things that worked in processing are working on the Arduino, too...I still have to deal with my inputs and have cut back my memory useage a bit. I am running at 67% RAM at the moment and still have three more ideas for games. One is supposed to be a simple rythm based game, one more or less a racing game and finally a stealth based dungeon crawler. Looking forward to it!
