Cory Arcangel is an artist that is known for his video game modification art. He tends to take old video games, adjust them in some way, and present the often brilliant results.
One example of such work is Super Mario Clouds where he modified old Super Mario cartridges and removed everything but the slowly moving clouds in the background.

Though perhaps not a groundbreaking technological achievement, Super Mario Clouds was the artwork that inspired me to start incorporating digital media such as video games and animations into my art.
