The Minnow/Aquarium project is made up of two parts:

Minnow - A “toy” general purpose programming language with a Ruby-inspired syntax with actor primitives baked in, mostly to experiment with syntax and compilers.

Aquarium - The supporting library for efficient actor-based programming.  Aquarium current features:

• Low overhead actor creation, actor deletion, and messaging between actors
• The ability to isolate actors who might be unable to guarantee returning from library calls in a timely manner.
• Automatic re-balancing of the actor workload across schedulers
