I've really learned a lot from many of the libraries and code samples shared in the forum (I'm looking at you crawl space games!)

I thought I would add my modest contribution -- a library of additional eases/transitions/tweens for corona.

You can find it here

https://github.com/loghound/Corona-Transitions

To use simpley replace 'transition' variable with one from the library.

To see an interactive plot of the functions go here or you can look at a static plot below.
