Sam J shared this record cover (younger readers may not recall what a single is) from Brighton band The Upper Room. It’s some kind of a thematic map but I can’t find out what the theme is, the album cover is also a thematic map
The album art, an image of the United Kingdom made up of green dots, was based on a survey taken of O2 customers. The size of the green dots indicates the percentage of people who have a garden in each area, and the shade represents the percentage of seasonal affective disorder sufferers in each area.

That’s pretty geeky cover art
