GPUs ?, OpenGL ?, android ?, php ?

  1. What about coding on GPUs, android, php for interactive websites?
  2. GPUs and OpenGL - probably yes, is there time? I have allowed optional homework extensions for students with OpenGL and GPU experience.
  3. Android, interactive websites - I allow use in educational site projects, do not plan to teach. Have one project going in each, but in both cases the student came with the knowledge. (I need to learn new things too.)
