Words from the author:
all the graphics I did in Koala Painter was done with a joystick, as I didn't have a KoalaPad or a mouse. Later I switched to Zoomatic and did my C64 graphics with the keyboard, cursor keys to move (and the c64 only has 2 cursor keys, you have to hold shift to switch between left/right and up/down) and 1-4 to set coloured pixels. My C64 graphics from mid 1992 until late 2006 were all done that way, with the keyboard.

This picture by me called Summer in the City from 2006, that was the last picture I finished that was drawn that way, it was pixeled from scratch at the party where it won the graphics competition, I wasn't going to release anything at the party but on the way there I changed my mind and asked TDS if he could meet me in Oslo and bring a floppy disk with Zoomatic, just in case, and I met him there before going to Sweden for the party. Once there I borrowed a C64 from Taper/Triad, but because the guy who coded Zoomatic (Olav Mørkrid/Panoramic Designs) had a war going on with a Swedish demo group he had made it so Zoomatic wouldn't work on a C64 with a Swedish char ROM, and so Iopop/Triad had to go through the code and fix it for me so it would work on the Swedish C64 I was using. Fun times!
