We use a small bookshelf as a pantry, and to easily sort things I got a large number of nice clear containers.
This has led to the existence of a game called Grain Tetris: shuffling beans, nuts, rice, pasta, and so forth between containers in an attempt to have everything in a perfectly sized place.
Like real Tetris, it is a game one can never win, and also like real Tetris, it is weirdly satisfying.
