Pony is an object-oriented, actor-model, capabilities-secure programming language. It's object-oriented because it has classes and objects, like Python, Java, C++, and many other languages. It's actor-model because it has actors (similar to Erlang or Akka). These behave like objects, but they can also execute code asynchronously. Actors make Pony awesome.
