try stroking a selection with a brush

endless fun !

kaleidoscope filters, what would life be without them ? i think you should slow the animation down a bit though, it will produce a migraine if i look at it the way it is now.

I do that sort of thing when I can't think of anything else to do - make a mess with fancy brushes then run a load of filters on it.

N ot an animation but stroking a path combined with brush dynamics can come with some interesting shapes. Much improved since Gimp 2.6

This is using a 'comb' type brush, could not be much simpler.



Looking at the brush dynamics, again the simplest of options , only colour and fade

but then try adjusting some parameters, obviously the fade length, also brush angle, the repeat option and the gradient. Also try a containing selection and also the selection with a large 'feather' value.

As Esper said great fun
