Not sure if Vimeo works since youtube seems to hate Openings these days. But Durarara. Both OP's were great, but the second one really took the first place

I've got plenty of OP's i find awesome. but the list may get a bit too big.

eureka"s are definitely somewhere in my top ten.
taptiptap,
there is the fantastic ending of samshamploo by nujabees and a group of girls,

Carnival Phantasm. How could i have forgotten that one... Definitely very entertaining.
