"Things You Wouldn't Know If We Didn't Blog Intermittently."
My brain refuses to see them as perfect circles. I am aggravated at it.
Well, I just happened to have a soft drink top sitting there that was the same diameter as the inside circle and when I held it up to the inner circle it exposed the fact that it is an oval, not a circle. Just to make it official, I took a ruler and found the outside diameter going east-west was 5 and7/8 " while the north-south came in at 4 and 7/8".The larger circle is oval as well, just not quite as drastic.
Does the same thing happen on your monitor when you view the images at the link??
Yes, that is where I tested it, but while I was at lunch I determined that it was possible the settings on my computer monitor are skewed, like Panvision, so I printed it off. Perfect circles!
I copied the image into Photoshop and used the measuring tool. 244 pixels width and height for the interior of the inner circle and 351 pixels width and height for the interior of the outer circle. They're definitely circles. Wish my eyes would interpret them that way without needing to rely on tools to confirm it. Sure is weird.
Optical illusions like this really tend to make me feel like my brain isn't working the way it should be.
