CodeSimian was designed as a normal Java program.
Edit by : CodeSimian is a single JAR file smaller than 2 megabytes, and the program starts when you double-click it.

To download and use CodeSimian, click CodeSimian.jar then click Open -or- click Save, find the file CodeSimian.jar, then double-click it.

A unique feature is the ability to cast objects to unrelated types. You can cast the code: +(105 107 109 111) to a java.awt.Component, and you get JTree containing 4 TreeNodes. 1 TreeNode for + and 1 for each number. When you click the +, it shows the 4 numbers below it. Or if you cast it to a String, you get ikmo. Cast it to a float[] array and you get new float[]{ 105f, 107f, 109f, 111f }. New types to cast to can be added at runtime.

You can open CodeSimian.jar to see all the files inside it, because CodeSimian.jar is a ZIP file (easiEST to rename it to CodeSimian.zip and double-click it). You can read the .java .cs and .txt files (inside CodeSimian.jar) as plain-text, but the .class files and MANIFEST.mf are the executable program inside CodeSimian.jar. you can free download CodeSimian 0.65 now.
