Welcome to xinaesthetic.net. Here is an application for exploration of the parameter space of a graphics synthesiser. Your motions are followed and used to determine the fitness function of a genetic algorithm which breeds new offspring to replace those you do not pay attention to.
Click here to download and run the java webstart application.
Instructions
Move the mouse over different parts of the grid to register interest in particular configurations.
The borders fade from green to red, depending on the amount of attention they are given. When they go far enough into the red, they are replaced with new offspring based on the others that are currently around. Influencing the evolution of the population in this way is the main mode of interaction.
Additionally, moving the mouse over the large view to the left causes the evolution process to pause, such that the form may be examined without the pressure of the current population changing. Holding the control key while moving the mouse holds the currently focussed specimen, so that you don’t have to carefully dodge with the mouse if you don’t want the large view to change.
Each individual view can also be manipulated by dragging the mouse:
- Left click & drag for rotation.
- Right click & drag for translation.
- Middle click & drag to scale.
- Hold left & right buttons and drag to rotate about z.
- Alt & click to reset view.
There are no alternatives for mice with less buttons for now; sorry. All comments are appreciated.

thats pretty cool and it runs perfectly smooth, keep up the good work!
Very cool indeed! I am a graduate student in Psychology and need some abstract stimuli for a research project I am working on. I wonder if you would be willing to provide me with your source code (Of course, i would acknowledge you in the author’s note should my work be published!)
Hi Jon,
I only just noticed your comment – as you can see this site is a bit neglected at the moment and also I don’t get email notifications from it for some odd reason that I’m about to hopefully fix. Thanks!
If it’s particularly the graphics code your interested in then it is very simple fixed function OpenGL. There are is basically a nested for loop, with a transformation applied and a sphere drawn at each iteration of every level of loop. The visual effect is a combination of two (IIRC) coloured lights and additive blending. If you know OpenGL at all, that might make some sense…
I’m happy to share the code for this if you’re still interested; I might even be tempted to put a new spin on it just for you since it’s always nice to have friendly comments.
I’m always promising myself to do more little eye/ear candy things, much of which I’d not be averse to open source… watch this space!
Cheers,
Pete
