A few nice Arduino images I found:

The display module connected at the back and floating on the foam pad with the face of the display slightly proud of the front face of the box. Note the silver circles in the corners of the box. These are magnets and the frame has a clear perspex front which attaches via these magnets. The foam ensures the display is pressed hard up against the paper which is sandwiched between the frame and the perspex.
