This is cool. Can we use it for games?

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 :
- open source it
- add / change / remove functionality
- correct bug
- make it as a community project if people want to participate
- etc.
Since the script of the animation is just data, I think you could use it with any renderer (Java2D, OpenGL, other languages, etc...)
This ain't a game, I think it shouldn't be here

Oh right, could it be moved to the shared code section if a moderator read this?
