My inverter board died and I had to find another method to edge light the acrylic, so now, the main surface of the table is a back light itself.  There is an LED ribbon around the edge and the edge has been sanded and torched with a MAPP gas torch so it is smooth and transparent.  I’m still working out how to put a barrier around the edge for the lasers and the whole thing is scotch taped together at the moment.
