Bluebottle (formerly known as AOS and now as A2) is a modular, object-oriented Operating System with unconventional features. It has automatic and garbage collected memory management and provides soft real-time features and is developed at ETH Zurich. It is the next generation Native Oberon, the Oberon operating system [2][3][4] for bare PC hardware. It is small and fast and supports multiprocessor computers. It is completely based on an upward-compatible dialect of the Oberon programming language called Active Oberon. Its user interface supports a "point-and-click" metaphor to execute commands from text, similar to clicking hyperlinks in a browser. The interface is a zooming user interface. More and detailed information can be found in the Russian Wikipedia article about A2 (operating system).
