Irei mostrar exemplos como essa poderosa ferramenta que é a Biblioteca GD pode fazer.

Folha

<?php$width = 1600;$height = 1200;$canvas = imagecreatetruecolor($width,$height);$white = imagecolorallocate($canvas,255,255,255);imagefill($canvas,0,0,$white);for ($n=1;$n<255;$n++) {	$green[$n] = imagecolorallocatealpha($canvas,0,$n,0,105);}$max = 80000;$p1 = 79;$p2 = 89;$p3 = 98;$x = 0;$y = 0;for ($n=0;$n<$max;$n++) {	$p = rand(0,100);	$xt = $x;	if ($p < $p1) {  $x = (0.85*$x)+(0.04*$y)+0.075;  $y = (-0.04*$xt)+(0.85*$y)+0.18;	} elseif($p < $p2) {  $x = (0.20*$x)-(0.26*$y)+0.4;  $y = (0.23*$xt)+(0.22*$y)+0.045;	} elseif($p < $p3) {  $x = (-0.15*$x)+(0.28*$y)+0.575;  $y = (0.26*$xt)+(0.24*$y)-0.086;	} else {  $x = 0.5;  $y = 0.16*$y;	}	$diameter = rand(1,15);	imagefilledellipse($canvas, $width-($width*$x), $height-($height*$y), $diameter, $diameter, $green[(100*$y)+(155*$x)]);}$i = imagecreatetruecolor($width/2, $height/2);imagecopyresampled($i, $canvas, 0, 0, 0, 0, ($width/2), ($height/2), $width, $height);header("Content-type: image/png");imagepng($i);?>

Atualizarei assim que fazer mais.

oÔ, OMG IS MAGNIFICT! CONGRATULATIONS ! (My english is Umrrivel)

ficou muito bom o resultado

gostei do code

Lista atualizada.

nice man....
