Anvil - Dynamically compiled, object-oriented language and environment, especially suited for web applications.
Avail - Multiply-polymorphic modular language with highly flexible syntax. Unique inheritance model allows multiple inheritance and polymorphism, constrained genericity, covariant attributes via immutability. Due to identityless nature of types, a type can have an infinite number of super- and sub-types.
bx - Language with objects, interfaces, parameterized types, no inheritance, operator overloading, generators, static instantiation, compiled to C; descriptions, source code, examples, compiler.
Class (Computer Science) - Growing article, with links to many related topics. Wikipedia
CodeSimian - Interpreted, with 1 type (all is data) only, made with Java; can be used as strings of its own code or as Java objects, code (even 1-line program) can write or modify other code; main purpose: write artificial intelligences that modify (parts of) themselves or write other code.
Dynace - Object-oriented extension to C language. Solves many of the problems associated with C++.
JellyJ - Project to create object-oriented language that is easy to learn for beginners.
Kapsel - Experimental object-oriented language. Looks and feels much like original Smalltalk, adds features to specify access to object detail.
Lava - Experimental, innovative, object-oriented, interpreted language, and programming environment LavaPE; edits programs via syntax-sensitive point-and-click style structure editors, not text editors; parameterized (virtual) types, refactoring, static checks.
merd - Ruby-like expressiveness + static type checks, like Haskell. Open Source, GPL
merd: SourceForge - Practical OO language: Ruby-like expressiveness with Haskell-like static type checks. Coded in ML, runs on Linux. Open Source, GPL
Nice - OO language based on, integrated with, Java (compiler emits Java bytecode); features of functional programming, implements state-of-art results from academic research, for more expressivity, modularity, safety. Open source, GPL
Noobeed - Interactive geomatic object-oriented language for spatial modeling, image processing, remote sensing, digital photogrammetry, geographic information system (GIS), geodesy, and surveying and mapping.
Nosica - Syntax similar to C++, Java, advanced high level features: strong type system, automatic memory management, global code optimization. Development website, has some documentation, forum, announcement from developers, sources. Open source, GPL
O'small - Concise, simple OO language for teaching; and study of semantics of inheritance, and OO languages in denotational style, later became subject of research on type inference systems and abstract machines. Open Source
Qu - Full-featured, semi-dynamic object-oriented language. Open source, GPL
Superx++ - Compiled object-oriented language fully based on XML syntax; conforms to XML version 1.0 specification as published by W3C. Descriptions, documents, FAQ, downloads, links. Open Source, LGPL
UnrealScript Language Reference - High level, simple, Java-style, object-oriented, compile time error checking; native support for major concepts of time, state, properties, networking, which few languages address, to greatly simplify code. Mainly for games.
VIRT Laboratory - Makes paxScript: general purpose, imperative, object-oriented language, with new technology of dynamic data structure processing; lets one process dynamic data structures (lists, trees, more) effectively with no pointers. Ensures laconic and uniform notation allows hiding memory allocation/deallocation mechanisms.
