It's the underside of my yoga-mat-topper. Obviously. Lots of little rubber feet attached to a purple towel. It's definitely the most purple thing I own, though!
For earth, some earth! It's a flower bed outside the John Innes society meeting place. John Innes founded a garden business, and also a garden suburb, near where my parents live. They're most famous for selling compost! At a guess, I'd say this flowerbed has been fed some random leftovers over the years, as the local soil is thin clay with lots of brick dust in it, and this is distinctly more lively than that!
