+* Description
+Goal of this project is to show off capabilities of [[http://www2.svjatoslav.eu/gitbrowse/sixth-3d/doc/index.html][Sixth 3D]] engine. Also to
+show examples of its usage.

 Sample scenes rendered at interactive framerates by Sixth 3D engine.
 
 
-Sixth is presently in research / prototyping and ideas collecting
-phase. Some working parts are already implemented, and can be run as a
-demo or as a library in other projects, if you are computer
-programmer. System is far from being useful for non programmers (Pre
-alpha).
-
-
-Implemented and working features:
-- First layer of storage: Simple persistent key-value map.
-- In software, pure Java realtime 3D rendering engine.
-
-
-[[http://www2.svjatoslav.eu/gitbrowse/sixth/doc/applet.html][Run Sixth 3D/GUI demos as Java applet]]
-
-
-System is implemented in Java because:
-- It scales well to handle great complexity.
-- It is easy to refactor and experiment with.
-- It is fast enough thanks to Java virtual machine just-in-time compiler.
-- Easy to run on various hardware platforms and operating systems.
-
-** 3D rendering
-
-3D rendering is done in software, 100% pure Java on CPU. At least for
-now.  Modern CPU cores count keeps growing and therefore rendering by
-CPU is not as expensive as it used to be for the old single core
-systems.
-
-CPU rendering performance is already good enough to implement usable
-3D UI at sufficient detail level, resolution and frame rate.
-
-Pure Java also means easy portability and installation. No need to
-deal with platform specific dependencies.
-
-Also CPU rendering allows to easily test different rendering algorithms
-and retains complete control of every rendered pixel.
-
-* Vision
-- Human computer symbiosis to unleash full potential of human mind and
-  computer.
-- A tool to amplify human ability.
-
-** Key ideas from user perspective
-- Helps/assists in understanding, discovering, learning and creating
-  things by being very visual and interactive. (I think of
-  problems/solutions visually and I want user interface/experience to
-  reflect that)
-
-- Properly visualizes and immerses user in completely various forms of
-  information and provides intuitive and powerful ways to explore,
-  interact and manipulate it with fast feedback loop to immediately
-  see results.
-
-- I like this quote:
-#+BEGIN_QUOTE
-“Virtual reality holds the key to the evolution of the human mind”
-Dr. Lawrence Angelo, The Lawnmower Man (1992)
-#+END_QUOTE
-
-** Key technical ideas
-System should make use of distributed computing like SSI or/and Hadoop
-for greater performance and reliability.
-
-System should use some overlay network to enable secure and reliable
-and easy to use communication between any process on any networked
-computer as well as human to human communication.

-* Ideas to possibly consider/incorporate in the future
-
-- Semantic networks / knowledge trees.
-    - Is able to use natural language for knowledge mining and
-      question answering. This could potentially lead to self aware
-      artificial intelligence. Because of [[http://en.wikipedia.org/wiki/Three_Laws_of_Robotics]["Three laws safe"]] design,
-      there is nothing that can go wrong.
-
-- Become an alternative to or an integrated part of KDE, Gnome,
-  Canonical Unity or similar desktop user interfaces.
-
-- Become an open source scientific computing engine of structured data
-  as an alternative to proprietary Wolfram Alpha.
-
-- Become an open source solution for unstructured knowledge extraction
-  and processing, similar to IBM Watson.
 
-- P2P (Peer to peer) capabilities:
-    - File/data sharing system.
-    - Data streaming system.
-    - Distributed backup system.
-    - Distributed computation system.
-    - Communication system.
-    - Possibility of completely decentralized and stealth mode of operation for information publishing, storage and distribution, similar to Freenet.
