I took the day to create a bitmap animation creator in java. You can save your animation as script code and reload them later.
You can donwload the jar here
Here is an animation I made with it. Just copy it in the load section when you start the program.
This is cool. Can we use it for games? 
This ain’t a game, I think it shouldn’t be here
Anyway, thanks for sharing! 
Absolutely! I’m planning to use it as an in game animation creator for my next game MiniRunner It will be used by the player to modify how their character look. It seems a lot of people like to create unique things and look different than others. This stay true in game and is a reason why lot of player think character customization is so important. So, I will basically give them the opportunity to create an animation to make themselves unique!
If anybody tells me they want to use it, I could :
Since the script of the animation is just data, I think you could use it with any renderer (Java2D, OpenGL, other languages, etc…)
Oh right, could it be moved to the shared code section if a moderator read this?
