I dunno the logic math of your program, but AFAIK, array indices accept whole numbers only!

It's far from working right, but here's a patched version:

1. private static final float radiusCircle = 100f;
2. private static final float noiseVar = 0f;
3.  
4. private static float timer = 0f;
5. private static final float timerAmount = -100f;
6.  
7. private static final byte  noisesNum = 10;
8. private static final float[] noises = new float[noisesNum];
9.  
10. void setup() {
11.     size(400, 400);
12.     smooth();
13.     frameRate(30);
14.     stroke(255);
15.     strokeWeight(5);
16.     background(60);
17.  
18.     for (byte i=0; i<noisesNum; noises[i++] = i);
19. }
20.  
21. void draw() {
22.     translate(width/2, height/2);
23. 
    
24.     timer = timer + timerAmount / frameRate;
25.     float x, y;
26.  
27.     for (byte i=0; i<noisesNum; i++) {
28.         noises[i] = noise( (timer+i*.314f)*.005f, (-timer+i*.314f)*.005f, i*.314f*.005f);
29. 
    
30.         x = cos(i) * radiusCircle;
31.         y = sin(i) * radiusCircle;
32. 
    
33.         point(x*noises[i], y*noises[i]);
34.     }
35. }

Oh. I do that before or after pasting? I'd like to know how to have auto-numbering w/ HTML. 

" for (float i = 0; i < 10; i++) {"
As said, use int instead of float.

" noises[i] = new float[i];"
new float won't work: float isn't a class, it is a primitive type.
Perhaps you want noises[i] = float(i); (the float() function is Processing-specific! Illegal in Java...)

" translate(width/2, height/2);"
Beware, it is in setup(), it will done only once. draw() will reset it. So better move it there.

In general, unless you are aiming at a cumulative sketch, you want to call background() at the start of draw(), too.

Cheers GoToLoop for the reply, but the points all move together right? I am interested as I previously said to have a different noise variable for each point

Ok, so I created 2 arrays for X,Y and 2 arrays for different timings for X and Y. They seem to work alright.

Congratz bourdonprince !

Just a little observation... Within setup(), you have 3 for loops equal to one another. How about merge them into 1?

for (byte i=0; i<noisesNum; i++) {
    noisesX [i] = noisesY[i] = i;
    timingsX[i] = random(.05f);
    timingsY[i] = random(.05f);
}
