Here's a video showing experiments using color mapping instead of color modulation, mostly. No 3D effects are enabled in this number.

Hi Steve
Thanks for the message. I don't have the laser (as yet) I was hoping to read up about it before possibly obtaining one. I had a Laser Physics Reliant WC300 back in the day, sadly long gone - lovely little laser :-)
Best
Simon
