at the end of the vid it looks like the other video icons are spinning. :O

Watch entire video. Look at your hand. Your hand is now a spiral galaxy. Trippy!
see all

Beautiful, but where is the h2? I only see stars and dust...
-
After watching this comments started to spin for me :) nice
-
cool, though not technically a simulation. more of a demonstration/visualization of a theory.
-
This is with full interstellar gravity?
-
thank you very much for your reply to my previous questions.

You didn't consider the gravitational effect, of "Dark Matter", on the simulation :)

Thats not entirely true since the gravitational effect of dark matter is implicitely contained in the radial velocity curve. But this is just a simulation of the visual appearance anyway.

My bad, since the article is unfinished i didnt upload any code. I have fixed this and the download link should work now. The code is for linux and requires SDL/OpenGL. In order to compile the code right away you need the CodeBlocks IDE.

Sorry, i have to disappoint you. This is not a n.body simulation. The stars simply follow elliptical orbits that are rotated against each other with increasing radius. This was meant as an illustration to explain why spiral arms are stable (more details and the source code can be found at this page: beltoforion (dot) de (slash) galaxy (slash) galaxy_en.html (its still pretty incomplete)
