That's so cool... only 3 entries in and the standard is really high already. Phil

Cool idea. I assume the fan was running, to get the effect... I wonder if it wouldn't also be interesting to try with the fan stationary.

Yes. The laser was taped to a short length of welding rod chucked in the drill so I could change the sweep by bending the rod. I this case, it swept a ring slightly larger than the height of the fan. I slowly swept the laser ring across the fan in serveral passes to get this effect, which was the best looking of about 60 attempts

So you spun the laser with the drill? -- Victor
