Start with a 512x200 RGB image. Run a plasma with default turbulence. Make a 512x200 grayscale image. Using the text tool, make a large piece of text in the gray image. Add noise to the image (value 80). Gamma the image at 0.4 twice to darken things up. Now, from the plasma image, run "bumpmap" with the grayscale text as the mask and a depth of 4. It should kick ass.
This can be extended by using the original text as a mask for compositing another texture into the final image.
I uploaded a bunch of the resulting images...

Pick a nice font (utopia sorta works) Make the text bold..and rather
big...now, trace the edges...next blur it.
You'll have to fiddle with the effects a bit to get it right. For a really funky effect, make a second copy and overlay it with black.
For an example, check out the title graphic on
I'm just starting to get to the point where I can actually *accomplish* stuff in the GIMP (thanks for making all the tutorials/tips/etc available!), but I wanted to have a 'cloud' (kind of an electric, disturbed cloud thing) as a halo instead of the glow in the tutorial on Zach's Tips & Tricks page.
So, I duplicated the logo I was playing with, rippled it (amplitude of 5 or 6 or something), spread it (aroudn 4 or 5), gaussian blurred it, and messed with the gamma 'till I got the shade I wanted. A simple multiplication, and an eerie effect.

That's a very nice effect... I played with it and found out that it can look even nicer if you do the ripples in both the horizontal and vertical directions (to do the vertical ripples, first rotate the image 90 degrees).
A nice way to make a Mosaic look more 3d-ish is the following:
Take a mosaic, convert it to grayscale, threshold it till the tiles are white and the grouts are black... blur the whole mess, and use that as a bump map for Lighting Effects. Looks neat.
Another CHOP trick -- offset -x -y instead of +x +y for the punched text effect (on Zach's Tips & Tricks page), and multiply by some texture, then composite it onto something else using the original text as a mask. Nice rounded, raised, textured effect. Works well when combined with an offset +x +y, gaussian blurred, to make raised, floating, shadowed text.
[This is now available as a tutorial at this location.
Just a neat effect which may be totally useless, but here it goes :)
Create a new RGB image. Plasma Clouds it with turbulence set to about 1.5. Whirl. Oil Paint. Enhance. Whirl a bit more... looks somewhat Van Gogh-ish...
