This is what we are going to create:

This tutorial is written for Paint Shop Pro, version 9,
but should work fine in any version :)
Download a demo here: http://www.corel.co.uk/

You will need two plugins in order to do this tutorial,
please install them and restart your psp and you are ready to go :)
I will not give you any links to the plugin filters, cause the links change all the time,
so if you are missing a plugin - just google for it.

The plugin filters you need are:
VM Extravaganza (Ray Transmission)
Simple filters (Quick tile)

Okey... let's get started :)

1. Open a new image (File/New) with settings like below:

2. Floodfill with a dark color, I used #50619a

3. Use a light color (I used #c2bbf5) and with your paintbrush, settings like this:

draw a big "8" at your image like this:

4. Go to Effects/Plugins/VM Extravaganza/Ray Transmission with these settings:

5. Go to Effects/Plugins/Simple/Quick tile and press Apply

You should now have an image looking like this:

***Optional***
If you would like to have your background a bit different, you can follow these two steps:
Go to Effects/Plugins/Simple/4 Way Average
and Effects/Plugins/Simple/Top Left Mirror and your background
will now look slightly different like this:

You can also try different numbers for different backgrounds...

Finished!
