_Monocells

this is my first shot with processing, a simple field of random cells.
[applet+code] http://www.gramagrass.org/drafts/_monocells/
The cells behave randomly and moves away from the mouse pointer if your move it around. Clik+hold to attract the monocells to the pointer. It's a simple algorithm (with a lot of work for tweak and improvement, i guess). Any comments or suggestion will be appreciated.

Hi,
this is my first P5 code,
http://www.ghostagency.net/processing/arbor_1/
it's a simple recursive exercise just to practise with a new language, I used a sample (the rotation sistem) of the Cube_rgb example.
Bye

This code is tediously primitive; it won't even run as an applet due to the image retrieval operations employed. But I really wanted to do the simplest of things, so think of it has a kind of reverse hello-world.
Works great - needs a fairly large screen and a broadband connection.

Hi, this is my first post, with a link to my first (and 2nd) p5 code. I started with the idea of a displacement map / voxel engine sort of thing, and by not knowing exactly what I was doing, stumbled across an output that is simple to make but has a nice aesthetic.

my first (and only) sketch.
basically, it starts with 1 "pixel" thats 512 pixels wide/tall. then everytime you press a button on your keyboard it halves the hieght/width there by quatrupaling the resolution and redraws it, when you click the square size gets set back to 512
Code:
int resolution = 512;
void setup() {
size(512,512);
drawer (resolution);
}
void keyPressed()
{
if (resolution>=2)
{
resolution/=2;
}
drawer (resolution);
}
void mousePressed()
{
resolution = 512;
drawer(resolution);
}
void drawer (int rez)
{
int shade;
for (int i = 1; i <= 512; i+=rez)
{
for (int j = 1; j <= 512; j+=rez)
{
//shade=int(random(0xFFFFFF));
shade=int(random(255));
shade=(shade<<16)+(shade<<8)+shade;
for (int k = 0; k<(rez); k++)
{
for (int l = 0; l<(rez); l++)
{
set(i+k,j+l,shade);
}
}
}
}
}
void loop() {}

horribly coded but here it is:
//
void setup() {
size(600,400);
background(255);
noStroke();
ellipseMode(CENTER_DIAMETER);
}
void loop() {
float cr = random(255);
float cg = random(255);
float cb = random(255);
float a = random(30);
color c = color(cr, cg, cb, a);
fill(c);
float r = random(120);
float x = random(600);
float y = random(400);
ellipse(x, y, r, r);
// delay(int(r*2));
}
void mousePressed(){
fill(255);
rect(0,0,600,400);
}
