Ok, here is some fun stuff. I am sure you may have already seen some of these (The clock!). But this is for posterity's sake! If you still haven't seen these, check them out. (If you are in office, make sure u have earphones on):

-An arcade game
-Counter-Rotating Spirals Illusion.We used to do similar stuff as kids in school.
-Deng deng dong
-The by now famous clock
(All thru Mefi.)

Also, there is a new photolog at knurdle.com Pretty neat (via Photographica). New images in Thom Anderson's photography site. I like his stuff.
