About this Website (Technical)

This website requires HTML5 CSS3 and SVG (vector graphics).

It has been tested on Vivaldi, Chrome v18+, Safari v5+, Firefox v11+, IExplorer v9+
It may not display so well on older web browsers

The newer SWIM model requires javascript from summer 2021 or later
SWIM is coded using Scala3, compiled to javascript

Please contact me if you find problems.

Note: background SVG image may be affected by a bug in older versions of Chrome
