I am idly thinking about making a linux distro custom made for kids. (Also possibly people who hate computers and bad eyesight).
The basic premise is to create a locked down environment with content filtering for web, IM and email. Add to this a interface design with big, unambiguous buttons, some easy-yet-functional apps and some games.
A part of the idea is to remove all setup and config functionality from the apps and put it on a special interface with root access only, so for example an email program could be reduced to something like 5 buttons.
Yes, it wouldn't be the easiest thing to make, but I think its the kind of project you could get a lot of community support for.
I am still just pondering this, but I have wanted to get involved with distro making for some time so I am sort of looking at areas that are not covred by other distros. (Also, some intense messing with FLTK has led me to take an interest in the equinox desktop environment, and I think it would be suitable for a project like this)
So, does this sound like something you might put on your kid's machine, or your grandma's?
