Yeah, very cool part about Teeth's design; that his shades also double as eyelids - and his bandmate Floyd's shades also blink like eyes! All the EM have really uniquely designed eyes when it comes down to it - already mentioned Teeth/Floyd (and before Floyd's shades blinked in 1977, they originally were special in that they had the psychedelic lenticular effect), Animal has his eyes that widen and close, Zoot's eyes are perpetually replaced by sunglasses, Janice's are lids, and even later member Lips has his slanted look.
