Tetris Game

At the left it is the original tetris game. At the right it is the instrumented version, with an aspect deployed this way:

var pointcut = function(){
  return true;
};
var advice   = function(jp) {
 return jp.proceed();
};
AspectScript.around(pointcut, advice);

At the bottom of the page you can observe the number of join points the aspect has seen (and matched).
