"Ruby is a reflective, object-oriented programming language. It combines syntax inspired by Perl with Smalltalk-like object-oriented features, and also shares some features with Python, Lisp, Dylan and CLU. Ruby is a single-pass interpreted language. Its main implementation is free software distributed under an open-source license." - Wikipedia
Ruby feels like a powerful language that fits well for writing smaller projects and websites. It can probably also be used as scripting language for larger projects.
