Orange spiral

Hello everyone,
It took me quite sometime to set up the stage. The idea itself wasn't new. Had seen it in a magazine. But what the heck ... it looked cool! This image looks best against a black background as it has a dark grey border around it.
Here's what I was able to achieve:
EXIF data:
Focal Length: 30mm
Aperture: F/11
Shutter Speed: 8 sec.
White Balance: Custom white balance from a white card (the LED was light purple)
As always, comments (both constructive and destructive) are always welcome.
