At the end of June this year, those who do this sort of thing will add an extra second to the world’s official clocks to keep us on the right track.
This gets a bit detailed — which is where the fun is! — but in short it goes like this. We have two systems to measure time: our everyday one which is based on the rotation of the Earth, and a fancy-schmancy scientific and precise one based on vibrations of atoms. The two systems aren’t quite in synch, though, since the Earth counts a day as a tiny bit longer than the atomic clocks say it is. So every now and again, to get them back together, we add a leap second on to the atomic clocks. That holds them back for one second, and then things are lined up once again.
This has to be done every two or three years, so why not just adjust the length of a day or year or something? The detailed explanation is at Bad Astronomy. Link

This kooky yet innovative clock features a masked figure that contorts into the shape of numbers throughout the day, so your clock face becomes a miniature stage for interpretive dancers.
Called the Hone Hone clock, it is mesmerizing to watch, and will bring a sense of life to your boring old clock. Now, you’ll want to watch the seconds tick by all day!

I haven’t spent this much time watching a clock move in …a long time. Hans Andersson, who gave the Rubik’s Cube-solving robot, built this clock called the Time Twister.
Time Twister consists of two LEGO Mindstorms bricks communicating via Bluetooth. The master brick keeps track of the time and handles the minute digits. The slave brick handles the hour digits and the second indicator.

The train station in Osaka, Japan has a computerized fountain that spells out the time, announcements, and pictures in falling water. If you spend too much time waiting for the clock to display, you’ll realize what time it really is …time to find a restroom! See more pictures and video at the uploader’s site.

The Long Now Foundation is building a clock that is supposed to last 10,000 years, and chime with a different song every time it sounds. Danny Hillis invented the clock in 1995, saying
I want to build a clock that ticks once a year. The century hand advances once every 100 years, and the cuckoo comes out on the millennium. I want the cuckoo to come out every millennium for the next 10,000 years.
The 200-foot tall clock will be installed under a Sierra Diablo mountain on Texas land owned by Amazon founder Jeff Bezos. Right now, a robot is carving steps inside the mountain, and some of the larger clock components are being assembled. Read more about it at The Technium. Link to story.

Have you ever looked at a group of cheerleaders or acrobats and thought “I wish they would do something useful with all those fancy moves?” Well, now artist Billy Chasen has conceived The People Clock. It’s a digital web based clock where the digits are composed entirely of people. Instead of half past noon, now you can tell people it’s half past Susan. Link

The 35 mm film may be gone forever on its way out, but it can still live in our hearts and our night table as this digital (oh the irony) Film Clock ($99.95) from the NeatoShop. Shaped like a giant 35 mm cartridge film in yellow cassette, the Film Clock displays both the time and calendar in its "film leader" display.

What time is it? It’s about Pi/2 past 2Pi/3. You don’t need to know the geometric definition of this mathematical constant to know what time it is since it’s not a digital display.

This web clock from designer Jack Hughes displays the time like all web clocks, but it also changes the background to correspond to the hexadecimal color value represented by the numbers of the digital time. Watch for any length of time and it will change, although sometimes quite gradually. However, when I looked up #110927, I got a completely different color. The colors may be set for a specific time zone. Link -via J-Walk Blog
If you were impressed by QLOCKTWO, but were put off by the price tag, you might want to make your own! The materials total less than $100, but you need a bit of know-how to pull it off. Instructables has your directions. Link -via a comment at reddit
Dotklok is an open source digital clock that can display the current time in a Pong style and many other animations.
The motivation for DOTKLOK was to combine in one clock a variety of ways to show time — such as with words, graphics, or retro game displays — while providing a platform on which others can further develop unique timepieces.
This clock would be really neat for a puzzle enthusiast or anyone who wants a one-of-a-kind item on their walls. The clockworks come with five puzzle pieces attached and twelve more that you add in your own design. Link

If you’ve ever fiddled with electronics, then you’ll recognize the photo above as resembling the classic Simpsons 260 multimeter. But rather than measuring currents, the oversized device is actually a clock!
Alan Parekh of Hacked Gadgets created this awesome clock that keeps time and outputs a calculated current to each meter to display the "current" time (get it?).

The Aspiral Clock is a new type of clock developed by two London-based tinkerers, Will Aspinall and Neil Lambeth. The entire clock itself turns slowly over a twelve-hour period and a loose ball inside marks the current time.

New York-based designer Ji Lee’s Redundant Clock uses hands oriented toward the hour markings for its hour markings.
Browsing around Lee’s website, I also found this interesting work of guerrilla art. Lee puts empty speech bubbles over public advertisements and then photographs what people write in them.
Scientists have built a clock that is 100,000 times more accurate than the atomic clock currently used for establishing the official time around the world. It was developed by a team led by Chin-wen Chou of the National Institute of Standards and Technology in Boulder, Colorado:
The quantum-logic clock, which detects the energy state of a single aluminum ion, keeps time to within a second every 3.7 billion years. The new timekeeper could one day improve GPS or detect the slowing of time predicted by Einstein’s theory of general relativity.[...]
Chou’s team is one of several racing to build an atomic clock that can replace the current international standard, the cesium fountain clock. The cesium clock loses one second every 100 million years. Chou’s is not the first quantum-logic clock, but his uses aluminum and magnesium ions, which makes it twice as precise as its predecessors that used aluminum and beryllium.
To keep time, quantum-logic clocks measure the vibration frequency of UV lasers. Unfortunately, the best lasers we can build veer off their normal frequency by about one tick every hour, Chou said. To keep the laser’s timekeeping precise, its vibration must be anchored to something much more stable.
Pictured above is Chou with his quantum logic clock.

Artist Mark Formanek and his team of seventy assistants set up a huge wooden digital clock in a Rotterdam train station. It’s completely manual and the digits must be changed every minute by the workers, which is precisely what they did for twenty-four hours. Video in Dutch (presumably).
I’m not sure how it works, but this 8-ft by 8-ft clock by artist Miss Moun displays the time by selectively lighting up words in a poem. Three words are always lit, and each word represents either the hour, minute, or second. The piece is entitled “6 Is for Blossom”, and you can view more pictures at the link.

When you watch this video, you might think that this is a man standing behind a sheet of plastic, re-drawing the hands on a clock face every minute. Actually, this clock by designer Maarten Baas is a LED screen showing the artist doing precisely that on a continuous loop. The video is from the recent Design Miami fair, which ended on December 5th.

Students at the Technical University of Wroclaw, Poland, decorated the outside of their building with a giant LED clock that displays the time in binary. It consists of eighteen round windows, with green windows representing hours, blue windows representing minutes, and red windows representing seconds.
