From the "Out In Left Field" department, here's an amazing video of a skyscraper being taken down in Tokyo, in an eco-friendly manner.

Here are the details from realestate.aol.com:

"The ongoing demolition of a Tokyo skyscraper makes it look like the 460-foot-tall building is shrinking. Taisei Corp., the construction company taking down the Grand Prince Hotel Akasaka, is using a new demolition technique, disassembling the building from the top down, floor by floor. No mess, no dust -- and it's eco-friendly to boot.

Workers are using the top levels of the building as an enclosed workspace supported by temporary columns that are lowered by jacks as each floor is removed. "

Here's how the "shrinking" skyscraper looks in time lapse photography:
