Creating Radials, Rays, & Stripes from the Center in Photoshop

How does one create stripes radiating from the center of the screen in Photoshop? You can do it manually but then you fight with equal spacing between each one. Here is the best way:
  1. Create blank document and choose your foreground and background colors.
  2. Create the stripes. Click: Filter-> Sketch->Halftone Pattern. Adjust "Size", "Contrast", and make sure the pattern type is "Line".
  3. Crop the canvas so that you see one half-sized A color stripe at the top and one half-sized A color at the bottom (B color is not at the top or bottom).
  4. Turn it on the side. Click: Image-> Rotate Canvas-> 90° CW.
  5. Now the magic. Click: Filter-> Distort->Polar Coordinates. Make sure it is Rectangle to Polar.
  6. (Optional) Add a white (or another color) to transparent gradient fx. Choose radial (or I prefer diamond) and try inverse or not.
Enjoy the hypnotic effects.

Awesome mini-tutorial! I needed just to do a slight change under Photoshop CS5: I started with a 512x512 canvas, and all I needed to do was to turn it clockwise and go to Polar Coordinates — no need to crop it at all.
