Have you ever heard the 1980 compilation album Miniatures? The gimmick is a great one: 50 tracks, by 50 artists, each no longer than one minute.
I took that as inspiration and ran with it, compiling 6 CDs of similar miniatures. For packaging, I filled each clear CD case with color-coded “miniatures” and used natural objects (a feather, a turnip, fingerprints) to stamp the CD labels. (This was back before we all learned what a bad idea adhesive labels on CDs turned out to be.)
