Light Arm

Step 1:

Make an image. press ctrl+d. Then get your gradient tool and set it to angle and mode to difference click around a bunch of times until you have something like this:

Step 2:

Press ctrl+u and set hue and saturation to the color you want. I used 38 hue and 100 saturation. Now make a new layer and make the background black.

Step 3:

Filter>Render>Lens flare and use these settings:

105mm Prime
Brightness 70

Step 4:

Now repeat step 3 except use brightness 60. You should now have a bright light in the middle of your canvas.

Step 5:

Now use Liquify and start from the center of the light and go to the corners. Change the layer mode to Hard Light and it should look like this:

Step 6:

With the layer that has the "X" made of light hit ctrl+L and use these setting:

Mode:RGB
Input levels: 0,3,255
Output levels:0,255

Step 7:

With the same layer go Filter>Blur>Gaussian Blur and set it to 2.5 to make the circle less grainy. Now press ctrl+u and set your color to the same thing you did before. Now your done!
