php - need ideas to only display some pixels and gray out the remaining pixels -

-

i'm looking ideas ...brainstorming new project client ....i have image ...300px x 300px ...i need display image 1 random pixel @ time until entire image revealed.

basically, @ intervals, pixel revealed , remains revealed while other pixels still blank. @ each interval, pixel @ random revealed , remains revealed join other revealed pixels. eventually, pixels revealed.

any suggestions on how make happen?

i make numerous copies of image , manually reveal 1 random pixel, surely can done programatically :)

oh, , cannot form of flash.

edit: realize mis-interpreted needed do, thought cool anyway , applied problem...

see working demo of following →

i threw in jquery. made each pixel 3x3 box instead because otherwise take way long process. seems work pretty on in client side, though haven't tested ie yet.

<div id="w">     <img id="i" src="yourimage.jpg" width="300" height="300" /> </div>  $('#w').css({     width: $('#i').width(),     height: $('#i').height() });  var htmlfrag = '',     id, ids = [],     removepix = function () {         if (ids.length) {             var rand = math.floor(math.random()*ids.length);             $('#'+ids[rand]).fadeout(function(){                 $(this).remove();             });             ids = ids.slice(0, rand).concat(ids.slice(rand+1));             settimeout(removepix, 1);         }     };  (var = 0, len = $('#i').height(); < len; += 3) {     (var j = 0, len = $('#i').width(); j < len; j += 3) {         id = 'pix'+j+'-'+i;         ids.push(id);         htmlfrag += '<div id="'+id+'" class="pix" ' +                     'style="width:3px;height:3px;position:absolute;' +                     'left:'+j+'px;top:'+i+'px;"></div>';     } }  $('#w').html($('#w').html() + htmlfrag);  removepix();
