I'll gladly accept any contribution. If you port a lesson, i'll add it immediately.

Just to be sure :
- all the tutorials have been implemented with GLES 1, isnt it ?
- if I understand right, porting the tuts to GLES2 would need deep rewrite, isnt it ?
- if so, do you think GLES2 fps would be very higher than GLES1 fps (say around 2 times faster) ?
- is there a way to display fps in the demos ?
- Yes, i have been using gles1
- The gles2 api seems to differ more and would require more changes. But i am definitely no gles specialist.
- I don't know
- You can run them from the command line (e.g. /opt/nehegles/lesson10 runs demo 10). You'll then get a fps display on the command line. But all the demos run roughly the same speed. If they use the depth buffer they run at ~50fps, if they don't use it they run at ~90fps.

Also if you port any of the existing demos to gles2, i'd really like to add it as well. It might be quite interesting to have a gles1 and gles2 version of the same lesson.
