Here's v1.1 http://forums.sketchucation.com/viewtopic.php?p=235227#p235227
It now has RayTrace AND RaySpray
RayTrace traces the picked ray from a start and incident point - it then allows 'bounces' to be made if there is a 'hit'...
RaySpray sprays rays out from a picked point, constrained in X/Y/Z-panes or full 3D with a desired angle of separation; there is only one reflection - no 'bounces', but RayTrace can be used over an earlier sprayed ray to 'bounce' individual ray-paths more if required...
All guide-lines/points are now grouped...
