over the course of an hour I managed to use most of the plugins in Gimp :
these are the results of just playing in GIMP (and 2 of these are seamless - good for texturing) 
thanks for looking!
I mostly like the ones with the “flames” (well, the stuff generated by the flame plugin :D).
It could be good as a wallpaper (althought it’s a bit blurry, maybe).
Amazing what the capabilities of Gimp is. Good stuff.
Nice one… can’t figure out what the seamless ones are :o
