This website is dedicated to free information, free software, free art and free services.

One main goal is the creation of a truly free open source computer game, called Uebergame.



Well a typical internet Blog, here you will find news, articles, personal experiences/stories, ramblings about god and the world, everything that does not fit in the other categories.



Art section contains artwork such as photos, textures, 3D models etc usable for game development or graphic design.

The art section is a bit more complex, so it has its own description page, so if you want to know more go to: https://duion.com/art/main



Main Homepage of the free and open source 3D shooter "Uebergame".

Contains direct download link, manual, infos, credits, links etc.



Contains links to our Mumble server and IRC chatrooms plus some description and  tutorials how to use it.



This is a collection of pieces of wisdom accumulated over the time. Researched from a broad spectrum of disciplines and by trying to be unbiased as good as possible. It does not try to convert you to a specific belief system, but tries to present the knowledge as it is.

Why call it "wisdom" ? Wisdom is applied knowledge. While knowledge is just things known, wisdom instead is lived knowledge that has been applied and put to the test, so there is experience behind it. This means it comes from the inside and is not just copied from somewhere.


This content may contain world view changing aspects and could cause severe cognitive dissonance, so reading is at your own risk.



Tutorials on how to do things, simple, direct and efficient, no bullshit like hidden costs, conditions or whatever.
