I had the opportunity to watch one of those things in action in the early '70s. It was about the size of the Silver Spade there and it was located in the central Pennsylvania coal region. It was really amazing to watch. I saw it both digging and getting moved. This one didn't have crawler treads - it had sleds that lifted it up, then it would move itself to the other end of the sled.
 
Yes, some of them moved by '' shoes '', actually they had a center 360° degree spinning platform and shoes which lifted the whole digger and slid foward. The big diggers needed two weeks for 10 miles. :scared:
I never had the oppournity to see such giant in action, but gladly there is youtube.
There you can see a dragline walking:

As I understand it, the one in Muhlenberg, KY was just abandoned when the coal ran out in that area. Was that common practice? It just seems a bit wasteful.

Taken from Paradise (Take me back to Muhlenberg County) by John Prine:
Then the coal company came with the world's largest shovel
They tore down the timber and stripped all the land
Well, they dug for their coal til the land was forsaken
Then they wrote it all down as the progress of man
 
I've seen pictures of that thing from a few years ago - seems it accidentally scooped up a parked Caterpillar D8 that the operator overlooked. The machine didn't even notice - it scooped the D8er, plunked it onto the conveyor, and up it went into the works. It only came to anyone's attention when the bulldozer fell off the conveyor onto the roof of one of the equipment shacks somewhere up in the stratosphere of that thing.

Are their any close ups of the actual bucket?
 
I don't get the point of making such a large machine. It can do work in one small area, then all the time and effort it would take to do the work manually, is used to move the daggum thing to another location. But that's just my opinion.

Are you serious? You must not realize the scale of that thing and the work it does. I saw it on an episode of Modern Marvels. They only move it when the quarry face it's working on has been completely excavated. That thing eats through walls of rock and coal like hell.
 
It's Hong Kong. Man, I've had some wild times in the Excelsior Hotel right there!
 
So that giant skyscraper that has Beijing written in neon and stuff about the Olympics is just advertising?
 
Yes. The Beijing Olympics is advertised everywhere here. The Chinese characters at the bottom of the sign say Hong Kong (Heung Gong). One character is obscured.
 
OK, LOOK AT THIS PICTURE.

Stare at the four dots in the center of this page for about 30 seconds. Try not to blink. Then lean back, look at the ceiling and blink your eyes a few times. Did you see Jesus?



REally COol!

Sure did. What does it mean if I'm not Christian...? :nervous: ;)

Here are some more optical illusions. Specifically, these are impossible objects:
