I can't understand why the beam isn't visible inside the glass block though (there's a small gap between the block and the floor). I notice on your prism Gordon that the beam isn't visible inside either. Please could you post your scene files for the prism - you've achieved something I've long wanted to do, the dispersion of a white beam into the spectrum? (Previously, I used the LW Nitisara plugin but had only limited success with it).
