I was thorougly impressed by the gl matrix screensaver written by Jamie Zawinski and others. When screensavers were a thing in Operating systems, I regularly use these screensaver. In 2007, I tried to modifiy its code and get the letters in Malayalam!. Basically, I changed the file where the characters are taken and replaced it with Malayalam characters.

We used to show this screensaver in free and opensource events just to catch attentions. Some of my friends asked if this changed code can be upstreamed. I asked JWZ and he replied this to me. And he was ofcourse right.
