I love hyped-up looks they used in cabinet art, too. That's my favorite cabinet side art of all time. Kiwi recently said that it looks like something from the Herculoids cartoon and I have to agree. That's probably why I liked that art so much when I was a kid.
Here's the Centipede one: [link] Tempest had some insanely cool side art based on the abstract enemies [link] Galaga had some pretty nice art on the side, too: [link]
