This is a great design for a bridge. It retracts into itself like one of those rolly-polly bugs. It’s creator is Thomas heatherwick and it’s an award-winner as well as a fantastic addition to the grand union canal system in london. There are other movable canal bridges, but the rolling bridge curls up on itself to form an octagon by using hydraulics. Check out the video below to see it in action. It’s always nice to see a fresh take on an old theme. Turns out London bridges aren’t falling down, they’re just moving.

Sheds are not gadgets, but sheds do house and hold many of our gadgets. Over at an interesting site called Readers Sheds they like to showcase all kinds of sheds.

One that comes up again and again is the Tardis. They have literally appeared everywhere throughout the UK. Apparently these sheds are also capable of being bigger on the inside and get frequently attacked by Daleks.

In the days before satellites frantically transmitted data to GPS receivers, there was at least one similar device making the rounds in London during the 20s. The Plus Four Wristlet Route Indicator had put maps squarely onto users’ wrists. It works the way it appears, basically using rolled up paper maps that show the route of a particular area.

The driver just had to turn the two knobs, which turn the rollers, thereby moving the paper maps. This Wristlet can actually store about twenty maps making it a pretty comprehensive navigation tool…For the time. To see the Plus Four Wristlet Route Indicator, you can check it out at the National Trust House where it is on display until June 1st.
