breaking codes

building codes that is.
I know that you all are about to riot, now that I haven't posted in a couple days. I don't wanna cause a national emergency (no, actually...), so...
Anyway, it's hard to get anything done when you are working. You'd think that you'd be able to work in the evening, but it is very rarely ever so.
I have been looking for pictures of circular things for a transition sequence. Google images is of course awesome. Immolated pinata.
Does anyone have any suggestions? What is round? Don't all speak at once.
I already thought of some easy ones, but it's amazing how some images are hard to find. Like it's pretty easy to find a picture of a diamond ring, but they are almost always tilted so the hole is oval. There is a theory among visual cognitive scientists about how we store typical images in out minds. So if you ask a group of people to draw, say, a teacup, they will nearly always draw it a side view, with the handle in perfect profile, facing right. This can be seen if you search for images of teacups as well. So it's really easy to find pictures of, say, wells, but very few pictures looking down a well.
Here is a picture that's supposed to be an old plate of mushroom illustrations, but it looks like martians to me.
Peace out yo.
