The audio, On the Teeth of Wheels by Beat Frequency, is a sonification of the [[Stern-Brocot sequence#Quackery]]. It was discovered independently by Moritz Stern (1858) and Achille Brocot (1861), along with its visualisation, the Stern-Brocot tree. Brocot was a watchmaker, and used the sequence to find best approximations for gear ratios.
 
The book "A Treatise On The Teeth of Wheels, Demonstrating The Best Form Which Can Be Given To Them For The Purposes Of Machinery; Such As Clockwork And Millwork, And The Art Of Finding Their Numbers" predates the sequence, being written by Charles Étienne Louis Camus in 1749-1752, (and translated from French to English by John Isaac Hawkins in 1873), but shows a method relying in part on guesswork to achieve the same end.

signal(SIGINT).tap: { print "\e[?25h\n"; exit }
print "\e7\e[?25l"; # saves cursor position, make it invisible
loop {
my @x = DateTime.now.Str.substr(11,8).ords X- ord('0');
put ~.[@x] for @t, @b;
sleep 1;
print "\e8"; # restores cursor position
}</syntaxhighlight>
 
Finally a more minimalist version that shows three progress bars (hours, minutes, seconds):
<syntaxhighlight lang=raku>print "\e7";
loop {
my $time = DateTime.now;
put '#' x $_ ~ '.' x (24 - $_) given $time.hour.round;
put '#' x $_ ~ '.' x (60 - $_) given $time.minute.round;
put '#' x $_ ~ '.' x (60 - $_) given $time.second.round;
sleep 1;
print "\e8";
}
END put "\n";</syntaxhighlight>

Note that though this code does poll the system timer approximately four times a second, this is a cheap operation; the GUI update (the relatively expensive part) only happens once a second. The amount of system processing power consumed by this code isn't noticeable on my system; it vanishes with respect to the other processing normally happening.

Chapter 18 of the BASIC manual supplied with the ZX Spectrum includes two programs to implement a clock - each uses different timing methods. The first - using a PAUSE command to hold for a second - is far less accurate, while the second - reading the three-byte system frames counter - is more CPU hungry (since ZX Spectrum Basic can't multitask, this doesn't really matter). With a tweak, the second is shown below.
