The basic idea...

"The basic idea behind open source is very simple. When programmers on the Internet can read, redistribute, and modify the source for a piece of software, it evolves. People improve it, people adapt it, people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing...
...The Open Source pages exist to make this case to the commercial world."    - Introduction to Open Source -

* Antikythera Simulation

market download The Antikythera Mechanism is a small device constructed in ancient Greece around 150BC and it was mainly used for accurate astronomical measurements.
It's complexity -comparable to that of a 19th century swiss clock- is admired by historians and scientists and it is often called as "mankind's first computer".

"Antikythera Simulation" is an open source, interactive 3D simulation drawn with OpenGLES of the 2 best known models of the Antikythera Mechanism as developed by scientists, and in the same time a showcase of the capabilities of your android powered handset!
These versions are preliminary ones, without much attention to the relative gear diameters or vertical positions. However, the tooth count of the gears and the operation are accurate.

Make yourself familiar with your own history and the astonishing sophistication of this ancient device while pushing your android's Graphics Processing Unit to the edge!
Touch-pan, rotate and pinch zoom in the 3D model and let hardware acceleration do the rest.
Check how many frames per second your android can render.
It looks best on high-end devices. Tablets supported.
There is also a brief explanation and history note in the "about" section.

* No permissions required, open-source, no ads, totally free and hopefully bug-free
