This GIMP (GNU) tutorial demonstrates how to create a psychedelic background.

Notes
You can quickly Undo a step at any time by pressing Ctrl then Z. Alternatively, click a previous Undo History snapshot - Windows then Dockable Dialogues then click Undo History. In addition, to Zoom in (or Zoom out) of your image; from the top menu, choose View then select a Zoom Tool from the subsequent drop-down list.

Note
Ensure the Layers and the Undo History Palettes are visible, and then drag them into position over your workspace - (Windows then Dockable Dialogues - then click Layers and Undo History).

Launch GIMP & Organise Its Workspace & Palettes

1/
Create a New (Transparent) Image, and set the following Width and Height dimensions; (File then New - Ctrl then N). 

Alternatively, select Height and Width dimensions of your choice.





2/
Then from the top menu, choose Filters then choose Render then choose Pattern and then choose Diffraction Patterns. And from the subsequent Diffraction Patterns dialogue box, experiment with the settings, and then click OK.





Filter Notes
This filter lets you make diffraction or wave interference textures. You can change the Frequency, Contours and Sharp Edges for each of the RGB channels. You can also set Brightness, Scattering and Polarisation of the texture. There is no automatic preview, so you must press the preview button to update. On a slow system, this may take a bit of time. Note that result doesn't depend on the initial image. This is a very useful filter if you want to create intricate patterns. It's perfect for making psychedelic, batik-like textures, or for imitating patterns in stained glass (as in a church window). For personal results, play with the settings until you see a pattern you like the look of.

3/
Congratulations, your psychedelic background is complete, and it is ready to incorporate into your artwork.
