OpenGL Blending modes Processing test application

I was experimenting with OpenGL blending modes in Openframeworks when I suddenly realized I was doing it without any kind of reference. On the Processing forum I came across this post about a Processing applet created by the great Ira Greenberg specifically created to experiment with OpenGL blending modes more freely.


I fired it up and I was surprised by its semplicity and power, it really helped me a lot. I added some simple functionalities to it and the result is here.

Thank for your code Ira, it rocks!
