You can use components listed in the README of the repository to apply cool 2D Filters in your games.
Pull Requests (PRs) are welcome, I will gladly review your contributions.
The few filters that are defined now are just a demonstration of the library, refer to the code in order to learn how to make your own component. Then submit your creation as a PR if you feel it would be useful to others
I will write a bit of documentation on the repository to help with contributing to it.
If anyone wants to then move the scripts from that dropbox to GitHub, it would centralize everything in one place (some scripts will even benefit from uniform definition to parameterize them).
