World's Largest Treehouse

Think you had the world’s greatest treehouse as a kid? Well this guy’s got you beat. Horace Burgess’s treehouse is located somewhere near Crossville, Tennessee and stands over 97-feet tall thanks to the 80-foot white oak tree it was built around which also happens to be about 12-feet in diameter at its base. It has 11 floors, somewhere in the neighborhood of 8,000 to 10,000 square feet, a miniature basketball court and is held together by roughly 258,000 nails. If you can think of a better way to spend $12,000, I’d like to hear it. For more details visit usatoday.

The 21st Century Noah’s Ark - Lilypad City

This is one man’s answer to the threat of Global warming. The 21st century Noah’s Ark if you like, called a Lilypad. Award-winning architect Vincent Callebaut has designed a self-sustainable "Lilypad City" as a long-term solution to the problem of rising sea levels caused by climate change. A Lilypad City would provide a home for 50,000 people and would float atop water. The artificial island includes a lake, mountains, shopping malls and drifts on the ocean currents.

Discovery Channel Building with Shark

Discovery Channel is employing some toothy guerilla tactics to market this year's Shark Week.

For starters, Discovery Communications just hoisted a 446-foot-long inflatable great white shark to the top of its downtown Silver Spring headquarters.

The shark marks the return of the Discovery Channel's popular Shark Week series, the 19th year Discovery has aired a weeklong marathon of shark-related shows.

Discovery says this year's Shark Week marathon, which airs July 30 through Aug. 4 with daily premieres at 9 p.m. Eastern, includes seven new shark-focused specials. Last year, about 20.6 million people watched Shark Week, cable TV's longest-running programming event.

As for that gigantic shark in Silver Spring: Discovery says it took 6.65 miles of fabric to create the inflatable fish and 36.7 miles of thread to sew him together. And if it were real, the shark would weight about 84,000 pounds.

Funny Building

This funny looking building reminds me of weird Japanese capsule hotel.
