it's not complicated at all just look at the code.
there are just two files:
first: <body background="top.gif" bgproperties="fixed">
(this is the background with demolished buildings)
second:
<body background="middle.gif" bgproperties="fixed">
<font face="Verdana" size="1" color="#000000">
<STYLE TYPE="text/css">
<!--a:link { color:#000000; text-decoration: none; text-transform: none; font-weight: bold;}
a:visited { color:#000000; text-decoration: none; text-transform: none; font-weight: bold;}
a:hover { color:#000000; text-decoration: none; text-transform: none; font-weight: bold;} -->
</STYLE>
<div align="justify">
<b>September 11th, 2001...</b><br>
...etc.
and a frameset document for setting up frames.
