Don't worry, safety is in mind but you have made a very valid point. I hope this helps explain why it is safe and that it has been considered.
Thanks

In addition you will loose some intensity lost at the reflecting mirror, shutter, and the fog needed to make the laser visible creating the vortex affect. There are a lot of variations in these factors but the one I know I can rely on will only change if I change it and brings the laser well into safely limits and other factors will only bring that down further.

The point of the laser is less than 2 mm so divide the circumference by the size of the laser point to get a dissipation ratio. The laser comes closer to the brightness of a bright flashlight rather than the original brightness of direct sunlight because of this dissipation.

I know the diameter of the circle that is created by the reflector at the closest point anyone would be to the vortex, I use this to figure the circumference of that circle. The circumference is directly related to the dissipation of the laser and the biggest single factor we can get real numbers on.

In figuring the safety factor for the laser vortex it only takes some high school geometry and basic math.

That was actually a large consideration in using it for the Halloween display and general laser safety is covered on my site.
