Ideas? Arduino controled laser light show with RGB

.
Has anyone made or have info on making a laser light show?  I have an RGB module with analog control and would like to build a light show with full RGB control using Arduino.

I have found several projects to drive galvos for X-Y control but none so far have included color control.

Any pointers, links or suggestions welcome.

Thanks.

As per my knowledge it is purely software based.

Thanks for the link. I will review that.

I plan to make an actual show using galvos. I have an RGB Module of the type used in laser light shows already. I designed a circuit to modulate each individual laser and now that I have my CNC mill I can "carve" a circuit board. First step is just to build an RGB box to adjust the color using three pots (just for fun).

I also found some circuits to explore to let the CPU control colors along with the galvos. Some are totally digital PWM and some use an analog encoder driven by a servo ( a bit over kill and costly )

I know I could just buy a ready built but a) cost and b) where's the fun in that!

Please don't look into the bean with your remaining eye !

Do you want a laser light show or an RGB programmable display. They are completely different things here. An RGB will only light up with different colors. It's not going to create a beam of light you can bounce off rotating and tilting mirrors to create a laser light show. If you want a laser light show you'll need to use a laser. If you want different colors you'll need different color lasers all with there own set of rotating and tilting mirrors. But it's not like you'll be able to use a Red, a Green and a Blue laser to combine and get different colors. They just don't work that way.

But if you want to play around with teh RGB here is a project for you.
