Eventbox is a model of concurrent computation that is used to build thread-safe objects with arbitrary interfaces. It is [kind of advancement](#comparison-threading-abstractions) of the well known [actor model](https://en.wikipedia.org/wiki/Actor_model) leveraging the possibilities of the ruby language. It is a small, consistent but powerful threading abstraction which **integrates well into existing environments**.
