Default Complete Newb, project help

Hey Laser enthusiasts! i need some help and my knowledge of electronics is extremely low.

I'm trying to find a laser for some painting projects.

I need a laser that will project a single dot centered, and two rings, one at 12 inches and one at 24 inches. Preferably with US power supply and an on/off switch.

Any help would be greatly appreciated! this would solve 3 weeks of searching for a solution!

I can offer this much

Not exactly what you are looking for, but putting this in front of a small green laser you can get your point and circle, then move the pointer closer or further away for the second circle. My guess is you don't really need my help on this.

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Depending on the angle of defraction/distance the laser needs to be away to get the rings i need, this maybe just what i need!
