Below are a few Demos of interconnected hardware using MeeGo / Qt / Qt Mobility / QML / OpenGL / OpenGL2 and QML 3D (still being developed). Showing the same sode being utilised over various devices but majority of changes are simple changes to QML for the User Interface (UI) for different input mechanisms or screen resolutions. This inter portability is where MeeGo / QML does excel and this functionality is built into the OS at the ground level opposed to utilising workarounds or add on patches.
This is a MeeGo prototype Demo by Nomovok showing examples of how they can run similar programs over different User Experiences (UX) using Qt ,QML and OpenGL Shader.
Looks good doesn't it ? Please let me know your thoughts in the comment box.
