Open a new document. I used 400x300.

Create a new layer.

Press D to reset your colours then X so that white is your foreground colour and black is your back.

Now select the gradient tool, and settings as seen below

Go crazy on the screen, do about 20-30 or more untill you have somthing like this.

Now go to Filter>Stylize>Emboss.

You will need to have play around with the settings for it to work with your image, however they should be similar to this.

Now hit ok,

Press Ctrl+G, make sure the colourize box is checked and, colour to your liking.

If you want goto Filter>Blur>Radial Blur

Use settings similar the ones below to get a slightly different effect.

The picture below shows how the radial blur effects the image

Well that's it from this tutorial, hope your had fun and learnt some new things.
