 ====== Tetris Game ======
-At your left it is the [[http://www.gosu.pl/tetris/|original tetris]] game.
+This is a demonstration of how the overhead introduced by AspectScript in an interactive application is negligible. Please try the game and let us know if you feel any noticeable difference!
-At your right it is the instrumented version, with a global aspect deployed (the pointcut always returns true).
-At the bottom of the page you can observe the number of join points the aspect has seen (and matched).
+On the left it is the [[http://www.gosu.pl/tetris/|original tetris]] game, unmodified.
+On the right it is the instrumented version, with one global aspect deployed this way (the pointcut matches all the join points it sees and the advice just proceeds):
+<code java>
+var pointcut = function(){ return true; };
+var advice   = function(jp) { return jp.proceed(); };
+AspectScript.around(pointcut, advice);
+</code>
+The counter below the game frames shows the number of jp seen by the aspect.
