Radiation with healthy glow

STEP 1

Start a new image and add your text, assuming white text on black background. Center the text and make sure you have a decent margine around it for the rays to go.

STEP 2

With the lower, white text layer selected, apply a Polar Coordinate conversion. Go to Filter>Distort>Polar Coordinates... Accept that the layer will be rasterized. Set it to convert from Polar to Rectangular.

STEP 4

Since we want rays of light, we can achieve this effect with Wind. But because Wind only goes side to side, we need to rotate our canvas. Go to Image>Rotate Canvas>90 CW.

STEP 4

Apply Filter>Stylize>Wind..., Method Wind, Direction From the Right. Apply it again, in the other direction. Rotate back like in step 3 and apply the Wind filter again in each direction.

STEP 5

Apply Filter>Distort>Polar Coordinates... and convert from Rectangular to Polar.

STEP 6

Add a color balance adjustment layer (Layer>New Adjustment Layer>Color Balance...) and adjust to emphasize green.

And there you have it, the final version is easily cropped out. You may want to try blurring the layer a little, though I like the sharp rays in this case.
