Post subject:  Imagepolygon Stars (Now with pic) [56K WARNING] 
I'm on a roll here. Playing with imagepolygon() stuff, I came up with a nice function to make stars.. function star($number_of_points,$outer_radius=100,$inner_radius=40) {
$p = array(); $degrees = 360/($number_of_points*2); for ($i=0;$i<$number_of_points*2;$i++) { $cos = cos(deg2rad($degrees*$i)); $sin = sin(deg2rad($degrees*$i)); $x = 0; $y = ($i%2==0)?$outer_radius:$inner_radius; $pї] = $cos*($x)  $sin*($y); $pї] = $sin*($x) + $cos*($y); } return $p; } Small isue with it at the moment coz it doesn't work with the rotatePolygon() function I posted yesterday. I'll fix it eventually. Unless someone else does. Made a groovy pic using this function:

Wow that is pretty cool. I couldn't work it until I looked closer and saw that the whole picture is made from stars. I like cool code like that... I hated maths at school but now with programming I see why we learnt it and how it can actually be pretty fun... Nice one
