A blend of Ruby, openFrameworks and a clean consistent syntax, Zajal is a staggeringly awesome creative coding tool.
The easiest way to get started is to head over to the main site and hit the giant download button (Only Mac OS 10.6 or later is supported at the moment). This will download the latest build of the interpreter. From there, check out the documentation and the built in examples in Help>Examples to learn how to use the language. The sketch book is also a great resource.
If anything looks a little spotty, that's because Zajal is still brand new and under active development! Report anything amiss on the forums.
To get the bleeding edge, try this
$ git clone http://github.com/nasser/zajal.git
$ cd zajal
$ make
$ ./bin/zajal examples/complete-sketches/ballerina.rb
To build the Cocoa app, open frontends/cocoa/Zajal.xcodeproj
in XCode 4 and
build that baby out!
Just using Zajal and providing feedback on the forums is plenty. If you happen to be awesome and want to do more, bug reports, improved documentation, better examples, sketch book submissions and code submissions are all welcome.
