The image below was done with the shadowy script found under  File > Create > logos > shadowy

I found this script lots of fun and have been playing around with it for a couple of days now. You can use it for any font, including ding bats.

If you don't have any of these scripts or Fonts, they are included and zipped in the folder included.

For the sky, which would be the background I used the sunrise gradient which should be included as a default packed with GIMP.

For the text image I used the Valentine font which is also included.  caps work best for this font.
