And we thought the London bridges falling down was enough. Take a look at the rolling bridge! This London attraction crosses a small moat in Paddington Basin. The Bridge, which ingeniously curls into itself to move out of the way of oncoming boats, was designed by Thomas Heatherwick.

So this one-wheeled motorcycle - yes, one actually exists - was invented by 18-year old science geek, Ben J. Poss Gulak. It weighs in at about 120 lbs but packs a big wallop. Though it was recently featured at the National Motorcycle show in Toronto this year - and it also operates on a complicated gyro-stabilization system, much like the Segway - the Uno is far from being widely available.

One nice thing: To go forward you just lean in!

Uno. The bike recently turned heads at the 2008 National Motorcycle Show in Toronto, probably because no one could actually figure out what the hell it was. Rather than the usual front and back wheel configuration, the Uno uses two, side-by-side wheels, rear footpegs and a much smaller chassis.

This strange little roadwork contraption seems to be a pavement striper. Never seen anything like it in my life!

Special thanks to OldOnliner for capturing it!
