Concept spherical coffee maker
That is, apart from the concept ones which, by nature, don’t exist yet. Not in production, at least.
Take this one designed by Kamil Kurka from the Institute of Art and Design at tehe University of West Bohemia.
I have to say I like the silver and black one the best, but it might also come in other colours. How good the coffee would be from one of these machines is another matter, but there’s no way of knowing that until it’s made.
