You can find them in the examples folder, and they are all runnable from within SBT. The easiest way to do this is to add a dependency on scalaz-example . You can then start sbt and load one of the example projects:

> project scalaz-examples > console [info] Compiling 1 Scala source to /home/michael/.sbt/1.0/scalaz-examples/target/scala-2.10/classes… [info] Starting scala interpreter… Welcome to Scala 2.10
