The document discusses different graphic design, video game, and radio production experiments the author conducted. For graphic design, the author created a poster advertising Coca-Cola using layers, backgrounds, and the Coca-Cola logo. For radio production, the author made a Halloween-themed Coca-Cola advertisement but notes the sound effects were too loud. For video games, the author animated a simple side-scrolling game inspired by Super Mario Bros. The author believes the poster best advertised the product due to its simplicity, and the radio advertisement was most professional due to fitting the Halloween theme through editing and voiceover.
