I really like this site - does anybody know how to make buttons like that?

it's a tween in flash, but anyway... I wouldn't know how to do it.
But why would you want to do that? If you would use buttons like that it wouldn't be original anymore. Those buttons are cool because you don't see them anywhere else.

I dont want to make buttons exactly like that, but if I understand how they are done, ill be able to make stuff just as cool myself, or use the effect a little different!

Actually I dont se it as a simple flash tween - ive tried that a million times using both images createt in photoshop and plain flash graphics - it didnt come close at all!
