Processing is an open source programming language and environment for people who want to create images, animations, and interactions.
- Processing. There are a few different versions to choose from: 2.0b6 (pre-release) and 1.5.1 (stable). The beta occasionally has a transparency issue but I'm not sure how to reproduce it.
- The stable version gives me this warning in Windows 7:
Display 0 does not exist, using the default display instead.
