Globigerina

Sort pocket things into chambers of growing size

A catch-all built like a foraminifer, the plankton that grows its shell one larger chamber at a time. Four round chambers spiral out from 30 to 64 mm, sharing walls where they meet: coins and pins in the youngest, keys and earbuds in the middle, wallet and glasses in the largest.
