elastiC by Marco Pantaleoni is an Object Oriented Programming language. In some aspects elastiC is similar to Objective-C and Smalltalk and can be interpreted or compiled to portable byte code. This language is easy to learn and it can be used to teach the basics of OO and event oriented programming or as a scripting language (for example in a 3D game engine - see the general 3d in opengl section).
