NetSurf 2.1 Kernewek Translation Wiki: http://treylyansow-kernewek.wikispaces.com/
I have recently started translating NetSurf 2.1 into Kernewek. NetSurf is an open-source lightweight cross platform web browser, undergoing active development and benefiting from awards from Google and their summer-of-code programme. It has a fairly succinct list of words for translation, so hopefully a Kernewek version should be fairly achievable (and having a completely translated web browser could be a useful stepping-stone for something like Firefox).
Unfortunately my Cornish isn't yet at a stage where I can be confident about my translations, so have created a Wiki to allow others to contribute to the project. If you'd like to help, please visit the link above. There's more information on the home page and you just need to follow the Kernewek link to get to the list of words requiring translation. The Wiki is unprotected so simply click the edit button to make your changes (no need to register).
Although translations are currently in Kemmyn, I'm keen for it to be in SWF/FSS.
