A stiff Englishman



This is work in progress. One of these days I will get around to finishing this and add a clock face.

Popelige Kiste (Bogey Box)


Popel is the German word for bogey. The only way to open the box is to exercise all of your your willpower and poke a pinky in the correct, hairy nostril.

TXT ME receives SMS messages and displays them, one letter at a time, by raising arms with letters on the end. Our world is getting faster and faster, so this deliberately takes its time and slowly “reads out” your message. You have to concentrate or you will miss a letter. You will find it hard to avoid trying to guess what a word will be when only a few letters have been revealed. Patience is required, it will not be rushed. If no one sends any messages, after a while it reads out TEXT ME as an invitation.

The Edward Snowden Academy of Observation


These penetrating observers are meant to peer at whoever is standing nearby. In 2014, everyone knows who Edward Snowden is and what he told us.

Can it see around corners?

Twelve Tweeters

A clock with roots that occasionally hoots. The time it can tell without even a bell. Ask it nicely and it will tell you precisely, but if no one’s around it won’t make a sound. A dozen on their perch won’t leave you in the lurch, the assembled dawn chorus will sing something forus. To make time a pleasure – a real treasure – not just something to measure.

To Tell The Time

Push the button – there are two parts to the time

  1. For the first part, the birds stretch their necks to show the number of hours from 1 to 12. You can look out of the window to see if it’s morning or afternoon.
  2. For the second part, each bird is responsible for 5 minutes, so for example, if the fifth bird sings that means twenty-five past.

Kim’s Amazing Ant Circus

There is an online version to try yourself. It’s best with Firefox, mostly works with Internet Explorer, doesn’t work at all with Safari.

It is a small Processing sketch using sound and the computer’s camera. The online version uses p5.js.

Sleeping Dog

An old English saying says that you should let sleeping dogs lie. Wake this one up at your peril!

Inspiration …

Kim’s dog

Kim’s dog can do a trick. If you squeeze its tummy, it opens its jaw. It’s a close relative of Mechanical Mutt.

Clothes peg bird

Take a wooden clothes peg, a dandy brush and a few other bits & pieces and this is what you get.

In the meantime she has grown legs and acquired a family – the Brush-heads (Familie Bürstenkopf)

Mechanical Mutt

This is like Kim’s dog, but it can do two tricks. It can open its jaw (press its right leg) AND wag its tail (press its left leg).

The shleep machine

As a 10 year old boy in in the sanatorium in Davos, Switzerland, we sang Brahm’s lullaby (Wiegenelied) every night before the lights were turned out and we were supposed to sleep. Counting sheep is supposed to help you sleep too. Fortunately, I can sleep on a clothesline.

Sing along if you like.

Guten Abend, gut’ Nacht,
mit Rosen bedacht,
mit Näglein besteckt,
schlupf unter die Deck’:
Morgen früh, wenn Gott will,
wirst du wieder geweckt.

There’s even an English version, which is new to me

Lullaby and goodnight,
With roses bedight,
With lilies o’er spread
Is baby’s wee bed.
Lay thee down now and rest,
May thy slumber be blessed.

Even Bing Crosby had a go (link to Youtube)
