do you know what an ambigram is? wanna find out?
well, you're in luck! nikita prokhorov, designer and teacher, has started the ambiblog -- completely devoted to ambigrams and the art of creating them. it's brand new, and already has some really interesting stories, such as an interview with john langdon, who created the ambigrams for the book angels & demons.
check it out! great art, fun (albeit sometimes confusing) for the eyes!
