Creative Code hackers and artful code tinkerers can cheer up. Because there is a new project coming at them: Zajal can briefly described by Ruby meets openFrameworks and OS-X in a graceful Processing-style. Currently the project is at version 0.3.3, the source-code is available at github. But people want to see examples to get an idea: here is the public sketchbook of Zajal.
One interesting aspect of this project is, that you can use Ruby and the full power of Ruby gems to develop your sketches. The design of the language is really Processing-like: to pick up and get started fast. Get results quickly. As you can see, that thing is also suitable for livecoding!
