This is a video timelapse (skip to 1:55) of a 57-story skyscraper being erected in China in only 19 days. The 2-million-square-foot (180,000-square-meter) building was constructed using prefabricated modules built at a factory and assembled on-site. Still -- 19 days, wow, I've taken longer to assemble LEGO sets before.
This building has 19 10-meter-high atriums, 800 apartments, and office space for 4,000 people.
Would you feel comfortable living or working in a building that was constructed in 19 days? Why not, as long as it's up to code. SECRET CODE. Think you have what it takes break the cipher and decode the message? Try this one on for size: RENOB. "That's just boner written backwards." Damn, the government would have killed for someone with your skill during WWII.
Keep going for the video.
Thanks to Patrick, who mentioned wanting to build a boat. Now we all know that.
