Physiogram, third take. And must admit I'm most satisfied with the results. This one was also done by covering the ceiling-hanging-lamp with alu-foil and made some holes in it with a needle (about five holes and two slits). The banding is due to 50 Hz electricity frequency. The lamp was swung into circular motion and the camera was simultaneously slowly rotating on a plate on the table. The lens used was 50 mm (80 mm equiv.) on a distance about 70 cm from the lamp - I like the close-up view, because the light fills the whole frame this way.
Edit was simple: topaz denoise, s-curve for contrast, usm 300%/0,2px, resize, border.
At first glance parts of this look like plaid cloth. Very cool ribbons created with your light source. Will be interested to see any comments on how you accomplished this after the challenge has finished.
