Okay, these are just 2 backgrounds I like to use. Here's how.

Background 1

1- Open new window with whatever size you use.

2-Click on the brush icon and choose GIMP Brush#2.

3- Brush Over Your Sig

4-Filters < Distorts < Polar Coords::Settings Circle Depth Percent = 0% Play around with the other thing

5-Brush Over Again

6-Filters < Edge Detect < Neon

7-Script-Fu < Animators < Rippling

8-Script-Fu < Alchemy < Erase Every Other Row

9-Filters < Distorts < Polar Coords

10-Settings < Circle in Depth Percent = 0.00% Offset Angle = 182. 40

11-Filters < Repeat "Polar Coords".

12-Brush Over Again

13-Filters < Edge Detect < Edge

This should be your finsished result.



Background 2

Simple but cool.

1-Click on brushes and pick GIMPBRUSH#5.

2-Brush Over the sig.

3-Script-Fu < Alchemy < Weave

4-Script-Fu < Decor < Old Photo(Should bring up new window)

5-Script-Fu < Alchemy < Predator

Finished result.



Thats it.

Nothing special, but I liked them.
*Saving them fucked them up a bit, they look much better when you use them in a sig.
