Thrown Effect
I have been trying to figure out the best way to make an object look like it has been thrown. Like a trail/tail. I was trying with smudge but it never turns out the best way because it needs to be a clean arch type effect.

Any suggestions?

RE: Thrown Effect
I also found a way that might work. I've been playing around with brush dynamics & brush creation.
http://docs.gimp.org/en/gimp-tool-dynamics.html

Brush dynamic custom brush FADE & SPACING/trail

1. First fuzzy select Fuzzyselect the background of your object.

2. Select > Invert (this will select the object)

3. Edit > Copy

((SIDE NOTE*:
only issue here is that whatever you copy will become a brush(temporarily) so you can also create a brush from copy if you wish, it will usually be created in the top row of the brushes. Clipboard brush is a quick way if you don't make brushes often though...

Creating new brush from copy:
Edit > Paste As... > New Brush...
brings up "Script-Fu: New Brush" window, enter brush name & file title (it automatically adds the dot part after like ".exe"
Ignore spacing(you can change that later...) Click ok
))

5. Then after picking your brush, click the reset icon (yellow arrow) next to the "Size" slider in the brush toolbox options. Make the slider bigger or smaller if its too big/small.

4.
=Opening the Brushes dialogue window (2 ways)
Click brush tool Paintbrush , then "Brush" types icon in the toolbox options.
(see below pic)
   
what you just copied "clipboard" will be at the top left of the brushes

In that same place bottom-right
open the "Brushes" Dialogue box by clicking the same icon on the bottom right Paintbrush

or "Windows > Dockable Dialogue... > Brushes "

5.
Next, Make sure your clipboard brush is selected in the toolbox options, then near the bottom of the Brushes window is another "spacing" slider. (this one you can adjust, others you have to make a new brush)

Adjust the spacing slider to however far apart you want the object to trail(you can test/draw the brush to see the spacing each time you change it.)

6.
Last,
to add the fade, either pick a default brush dynamic in the brush toolbox options "Fade Tapering" is good, or create your own (more control on fade vs. spacing but takes getting use to)

My map trail brush tutorail also covers how to make a new brush dynamic & brush but isn't specific to your "thrown" motion Situation.
I'm inclined to make one for just brushes & dynamics using my steps above since its pretty generic, so be sure to favorite my YT channel & stay tuned. Hope it works for you.
