Lots of interesting ideas about programming, simplicity etc.<br />
For example, Catclock was originally an X10 program by Tony Della Fera, Dave Mankins, Ed Moy, Deanna Hohn and Philip Schneider, crafted for entertainment, in the late 1980's. It was also ported to the Plan 9 operating system by Tom Duff. <a href="https://wiki.xxiivv.com/site/plan9.html" rel="nofollow">https://wiki.xxiivv.com/site/plan9.html</a><br />

There are several softwares available to aid this process, but most are either paid, difficult to use or lack some essential features. Also, many of the existing programs work only on a few specific operating systems and require installation by the user. Most programs only support 2D X-Y plots and so it is not possible to work with polar diagrams, ternary diagrams, microscope images or maps. With these issues in mind, WebPlotDigitizer was developed to be an easy to use, free of charge and opensource program that can work with a variety of plot types and images. This program is developed using HTML5 which allows it to run within a web browser and requires no installation on to the user's hard drive.<br />
