LDN24: Creative visualization at the Museum of London

This creative collaboration of The Light Surgeons(Production) and FIELD (Data Visualisation) consists of a 48 metre elliptical screen on which is displayed a large 24 hour clock:

From the Museum’s web site:

LDN24 follows a 24-hour day in the life of London with hundreds of filmed sequences from across the capital – framing the city waking, working and winding down on a giant plasma screen.

An enveloping stream of 35 real-time information flows around the LED ellipse producing an ever-changing map of the city. From tidal patterns to temperatures, flight arrivals to FTSE fluctuations, RSS feeds and live links to Google searches, partner news channels and Twitter keep an ear turned to the rhythms that compose the city. Software specially developed by the design studio FIELD choreographs the rituals and movements of London and Londoners into a compelling statistical dance.

There’s a movie too.

The Willis World Clock

This is the Willis World Clock in the London Science Museum.

I’ve not found out much about it, or who Willis was, but I did find a reference to a smaller versionin a 1939 copy of Flight magazine (here) and I presume the description is mostly valid for this version too:

The operation of this clock is extremely simple, with a twenty-four-hour moving disc in the centre and a separate minute hand below. The main face of the clock is laid out in sectors, with the names of all the more important countries and cities in the world indicated by arrows, and the time for each particular place is merely read cif against the appropriate arrow. The timing disc itself is clearly marked in a.m. and p.m. sections, so that, even when the twenty-four method of reading is not being used, there is no possibility of error. Those countries and cities where “summer time” arrangements are in force are printed separately in red type. For example, Great Britain and France have two positions, one at Greenwich time and one, for the summer season, on the mid-European time arrow.

Needless to say, such a clock will be useful in working out E.T.A.s which are likely to be at or near nightfall, and also for timing the reception of both weather broadcasts and others required for D/F bearings. The world clock is obtainable from J. H. Willis and Company, Ipswich Road, Norwich, and the aircraft or small marine type, for instrument-board mounting, is priced at 137s. 0d.

One of these – non-functioning, I think – was sold on eBay recently. You could have bought it for just £13.

More iPhone clocks

There must be hundreds of clock apps in the iTunes App store! And there are a few 24 hour dials in there somewhere.

The Astrock app is a software version of the famous Prague Orloj.

The Earthclock app is a re-interpretation of the Think the Earth watch, but still a pleasing design.

Developers: if you want people to find and buy your 24 hour analog dial apps, don’t expect them to scroll through pages and pages of apps in the App store. Why not let the connoisseurs know directly, by getting your app displayed on this site? (If it’s interesting and relevant to this site, I’ll give it a mention. If it’s just another boring 12 hour clock, don’t expect one!)

Clock in Bern: the Zytglogge

This is a recent picture of the Zytglogge, the astronomical clock in Bern, Switzerland:

You can read a lot about it at Zytglogge – Wikipedia, the free encyclopedia.

It’s hard to tell whether everything is working correctly. The picture was taken at 15:46 on Wednesday September 2. So the date seems right – the sun pointer at the bottom left is pointing to Herbstmonat 2, and the tiny window just below the top XII says Mittwoch. The other sun pointer in the zodiac ring is in the constellation of Virgo, which is also correct, I think. It’s only the time of day which I couldn’t easily find. That could be why there’s a simpler clock above it!

More iPhone clocks and watches

A few more 24 hour iPhone applications are appearing in the iTunes App Store. If you want to check any of these out, let me know how they work – I have no idea.

Here’s a familiar sight: the famous Shepherd Gate Clock at Greenwich, London. The Shepherd Gate Clock (this link is a link to the App Store) costs a modest dollar. I’m assuming that this is a genuine 24 hour analog clock. The time here is 20:10. It’s going to look a bit odd at midnight, with that sunlit brick wall…

This next one is a puzzle. It’s called iWatch, and it features an attractive rendering of three watches, including this Patek Phillippe watch with a 24 hour rotating dial. What looks like the hour hand is really the minute hand, and what looks like the minute hand is really the second hand. So the time on this picture is about 04:18:49.

(I’m not a big fan of the design, to be honest. The map is coarse, and that font isn’t attractive.) The real puzzle, though, is why this app is suddenly no longer available on the App Store, now that I want to provide a link to it.

The next app, nHands Clock, is a useful clock that lets you add as many hours hands as you like, with colour and labels of your choice. It’s a clever way of showing you the different time zones of people you know:

Finally, this excellent app is called 25h:

The idea is simple:

Feeling overstretched? 24 hours in a day is not enough? Then 25h is a clock for you.

Trick yourself into having 25 hours in a day. Get things done faster and have an extra “hour” for yourself.

Note that 25h does not modify time–space continuum (or your biological clock) to give you an extra hour. It simply makes the rest of your hours appear a little shorter so that enough time is saved for an additional shorter “hour” at the end of the day.

I know some people who set their watches fast – this is an interesting alternative.
