Saw a setup and result in the "Show your setup thread" for Physiogramns, figured I'd give it a try. Started out in my office, but it wasn't dark enough so I went into the garage. Used a small flashlight at first but then switched to one of my green lasers.
In the office I hung the flashlight from the ceiling fan and laid the camera on the floor (which made it a pain in the butt to focus). In the garage I put the camera on a tripod and put it high enough that I could get under it to use LiveView to focus, but low enough to give me a wide frame. Both times the light was shining down towards the camera.
With the laser I didn't want to take the chance of frying my sensor so I put the camera as high as my tripod would allow and aimed it at the floor. Had to get on a ladder to focus but it worked out pretty good.

...Tried varying exposures, but all shots were at f/8 and ISO100, and I also tried a variety of lenses; 100mm L macro, Nifty Fifty, and Sig 18-200mm OS. The Sig works the best because I can get bigger action. At first I used a short string and the swirls wouldn't get too spread out, but in the garage with more room I'm using a longer string so when I swing the laser the swirls get much larger. The only drawback there is that on one side the laser catches the expansion in the floor, so in some shots there's a break in the lines.
Anyhow...thanks for looking and enjoy.
