I have been making the laser vortex for several years as a Halloween affect on my front porch, everyone loves the affect. Finally, this year I created a Halloween site showing others how to make one of these. The video of this can be found on http://haunted.hyperreactor.net. Its made with a laser pointer, small motor, and a mirror creating an effect similar to what you might see at Halloween Horror Nights but on a smaller scale and much cheaper.
I have uploaded the how to videos and added them the the end of this instructable along with some example videos of the vortex in action. I have said this a hundred times but once again, it is even more spectacular to see it in person. There is so much depth that the video dose not bring out.

Signing UpStep 1: Laser Pointer Mount
We will be mounting the laser on a scrap piece of wood. The one used here is about 1 ½ by 1 inch and cut to about 6 or 7 inches. A 2 by 4 would also work well and can be found in your local hardware store. It will probably cost you less than a dollar if you need to purchase this piece.
A beam clamp was used to secure the laser pointer to the wood base and hold down the “on” button continuously. Three were used, two for securing the laser pointer in place and one to hold down the button. The one holding down the button should only be tight enough to hold the button down, if it is too tight it may damage the button. These beam clamps would be easy to find in the electrical section of your local hardware store near the electrical conduit for less than a dollar a piece. Just make sure there is a screw hole on the clamp to mount it to the wood base.

What I mean is that you need is a cylinder to mimic a tunnel, a cone would not work.
Anyway, you would need the smoke to be everywhere in that room for the tunnel effect, this also means that the more effective the tunnel is, the smaller it has to be.
