The Boston Museum of Fine Arts has an Egyptian Exhibit. Each time I have visited, I make it a point to dash up the stairs to view the statues and obelisks. An obelisk can look like the Washington Monument (yes, the designer copied the Egyptian obelisks), or it can be round.
On the last two visits (in 2004 and June 2011), I took pictures using a digital camera. The photos I took on both visits showed phenomena with one of the obelisks. It was so strong, it effected the statues next to it. At my 2004 visit at first I thought I had moved as I snapped the shot because a few of the photos were blurry. An inner urging told me to re-examine my pictures and I am glad because when I did, I discovered I didn't move while taking the pictures, the column and statues were moving! I carefully examined the surrounding areas in the photo, and there were portions that weren't blurry. If I made the mistake of moving; every aspect of the entire photo would have been blurred.
What is so remarkable about this whole thing is: an inanimate object isn't supposed to move on it's own. If something weighs a ton or more and moves, there must be an earthquake going on (at least that is the reasoning taught in school). What I am about to show you should not be able to occur, but my camera picked it up on two separate occasions, and there is one photo showing the obelisk 'swayed' to the side as well.
Below, you will see pictures of both visits. I present them in two forms: the original photo; and portions of the photos cropped and enlarged so you can see the vibrations. The pictures taken in 2004 are of poor quality because the camera was purchased when digitals were new to the market; but it's not so poor that you are unable to see something unusual going on.
This first picture shows a normal view of the obelisk.
In this second picture, I moved in closer and if you examine it, you can see that the base and the top of the obelisk are blurred. However; if you look at the statue next to it and the wall behind the statue, most of it is sharply defined.
And you can see that the obelisk sort of 'leans' towards the statue.
In this third photo I cropped the picture which 'enlarges' it a bit. Look at the top of the obelisk now. Even the head-piece of the statue next to it is vibrating. If you examine the rest of the statue, it looks fine.
I moved in a little closer below so you can see more. Is the shadow blurry? No. It is well defined.
In the photo below, I cropped the photo to highlight the bottom portion of the picture. If you look at the base of the obelisk, it is blurred. Once again; look at the statue next to it and the black cubes against the wall.
Below are the pictures I took in 2004. Look at the woman standing in the photo. She is sharply defined. Now look at the obelisk. Look once again at the top, the bottom, and also look at the leg of the statue in the lower left hand side.

Here is the same photo. I changed the color to black and white and placed arrows in red pointing to the vibration.

Finally; the same photo in which I tinted the photo green because it defines the outline a bit more.

So you be the judge. Put on your 'thinking cap.' Why is this piece of stone vibrating??
