Here is a little bit about each of the free software projects I maintain.
ColorTint
GitHub | GNOME Extensions Site
ColorTint is a Gnome extension that draws a translucent coloured overlay over your desktop. This is to help people with dyslexia, visual stress, scopic sensitivity, and related conditions. ColorTint was forked as AlphaTint for users who only wanted the ability to dim their displays. See Colour Overlays for Linux for more info.
KolorTint
KolorTint is a KDE widget that draws a translucent coloured overlay over your desktop. This is to help people with dyslexia, scopic sensitivity, and related conditions. It is the companion to ColorTint, a GNOME extension with the same function. See Colour Overlays for Linux for more info.
Pico RSS Maker
Pico CMS is a flat-file CMS based on twig and markdown. It’s great and I’d be using it now instead of Jekyll if it didn’t require PHP. Pico RSS Maker is a plugin I wrote so that I could have an RSS feed for a news blog for a client, mainly so I could tie it into Zapier routines. I no longer use Pico, but current users have improved the extension, in the FOSS way.
