What the picture shows

A pixel-art wooden crate or box with a light brown top and darker brown sides sits at the bottom edge of a mostly white image, rendered in a retro video-game style. Chatters likely use it to represent an item drop, loot box, or surprise reveal during streams.

No measured meaning yet. Used 50 times in 3 channels this month; one is written once chat gives enough evidence.
