Chipflip has a very thoughtful writeup of the recent Ready > Run exhibition in Philadelphia that discusses on what makes things chip art, and discusses how chip art can coexist with other methods and mediums in order to be better integrated with the artists vision.
These works go beyond the limitations of systems in several ways. There are physical interfaces that are not inherent to the systems. There are no NES-printers and therefore printed NES-graphics can only exist outside the system. There are unfortunately no lazer interfaces to the NES either, and it is possible that the hardware modifications by noteNdo produces effects and artifacts that are out-of-system-experiences; things that software and emulators can only (try to) dream of. The ideal glitches; those that cannot be reproduced or explained.
