Wow – Gomhi made these incredible little speakers out of actual eggshells! –

Handcraft loudspeakers using chicken eggshell as cabinet. They sound narrow, but I’m pleased about the result.
Driver unit is Hi-Vi B1S.

(I’ll kindly omit the usual “egg” puns) I’d imagine cutting the shell so neatly would be a rather delicate process – take a closer look on Flickr.
