The white in the eye...

My uncle could do it. (The uncle who was also able to blow smoke rings on request.) He could turn his eyes upwards and make it appear as if he had no irises, just white eyeballs in their sockets. Very scary and fun, back in the day. (Especially when combined with the smoke rings.)
Katsuki Tanaka has a little colleciton of people turning their eyes in this scary way on his website. look UP!. (No smoke-rings though) Not everybody in this experiment is really great at this silly trick. Bunny is best, isn’t she? How did I find this exciting corner of the web? The New Shift is out. It is issue Number 073 and I love the cover animation which is taken from a DVD by Katsuki Tanaka. This dance is called "uncertain". Excellent.
Oh yes, and then there was the wolf man. (but that’s a completely different story.)
