The theme of mine would be TV screen aberrations, such as signal distortions, broken light lines, chromatic aberrations, etc, but it only really remained an aspect on the visual side of the game since I didn't manage to fully implement it on the gameplay side as well. Were it not for time constraints I would have added a scoring board that would judge your final score for the six categories present (all based on important TV systems), and categories that got bad scores would disrupt the TV, so getting a terrible audio score, for example, would mean the music going silent and glitchy.
