These days we'd probably call it a "motion comic," but back in 1992 when Dragonfly Entertainment adapted Paul Chadwick's Concrete story "Watching a Sunset" into animation, they referred to it as a "video portfolio." It involves a lot of pixelated waves and trippy music as Concrete decides to take a walk and hang out at the bottom of the ocean (he's made of stone, remember) and maybe do a little light shark-punching. If you have fond nostalgia for the computer graphics and electronic music of the late '80s and early '90s, this one is for you.
