Hi Steve, Further to Marc's suggestion of laser pointers push through a dodecahedron. As the actual laser modules, rather than the assembled pointer, why not get a dodecahedron/icosahedron printed at Shapeways (or on your own printer if you've taken the plunge yet) with flat mounting points at all the vertices for laser modules to sit on. You could power them all up simultaneously for some fun (or final checks) but probably better from the pov of safety to just power them up as needed - don't want any headlines about audio guys getting fried by mystery laser devices!
