OK, spent some time with a new setup and adjustments. Any of these qualifiy to enter?

As long as the are 1" or more..

.. they would all qualify..
They all look good, as do your original ones. I's say - choose one and run with it:-)

ultravox

Agree. all.

Very very cool

twinbnj

They all look wonderful .

I like # 2 the best. It's hard to sau exactly why, but I think that desaturating the color is a mistake, and the composition on 2 looks more balanced; better centering, wider interstices in the light patterns, especially the warped grid section. Exceedingly cool.

cool photos, but how do you do that?

Do you remember SpiroGrahp?
First, let me say, these are really cool.

Reminds me of the old "art" set called SpiroGraph from my childhood (do they still make/sell these things?).

I do have to ask, how did you get the lines to trace so accurately? Something like this can be done with a long levered pendulum, but there is no evidence of decay in the applitude of the swing.

Wow ... good job. I love this type of stuff. I don't have the patience for it ...but I appreciate all your hard work.

Redhed

Very nice! How did you do this?

I love the one you entered. Really neat shots, all of them.

How to...
I should take a shot of the setup. The first series I simply tied a small led flashlight to some fishing monofilament and then tied it to the dining room light fixture. The line was only about 18" and I set the camera on the dining room table. Using a 12-24mm lens I played a bit with the zoom but could not get the pattern within the frame. Also the shortness of the line and longer exposures tended to overexpose certain areas of the lines.

Got feedback from the first set from you great dgrinners. Everyone wanted to see the full pattern. OK had to do a couple of things. Used a light stand to get height. Fastened a reflective disk holder to the top and positioned it 90 deg. to the stand about 5 feet parallel to the floor. This time I lengthened the monofilament to about 30". Setting the camera on the timer setting to allow me time to start the swinging motion I would fire, 10 sec, exposure started. In that 10 seconds I would start the pendulum motion of the flashlight.

Almost all of the exposures were 30 sec. I almost thought about longer but the I thought the light would become too dense and overexposed. The lens was set at f22, IS0 200 (could have dropped that a bit maybe). I would then examine the shot and adjust the zoom a bit to make sure the image was contained in the frame. Then it was trial and error, trial again until I felt I had a good sample of possiblities. Could have done it for hours...wife said come to bed.

The increase in length of the mono/weight of the flashlight etc allowed for the smoothness and very little loss of amplitude. There is a Focault Pendulum at the Oregon Convention Center with a huge weight and about a 50 foot cable. I would love to somehow figure out a way to shoot that with a light source attached to the weight:):

Yeah show us the little set up you have. I'm picturing you attaching a flashlight to a stationary object on the ceiling like a light fixture, killing the lights, tripping the shutter and letting the flashlight pendulum swing away.
