[Sugar-devel] SugarGames, GTK3 and fonts ?

[laurent bernabe]

I thought about translating my application into a Sugar Web applications,
but :

   - I don't know well sugar web library (sorry, I went to the developper
   page, looking at sources :
   http://developer.sugarlabs.org/sugar-web/README.md.html)
   - The resulting program will probably not be compatible with sugar 0.94
   to 0.98

Otherwise I am very interested in writing a sugar web version, using
KinectJs for example.

Regards
