Window over Window trick in PrBOOM

The example wad in this tutorial has a dead link, and I can't make total sence out of the tutorial. Would it be possible for someone to upload or point me to a wad with an example of this?

Thankx!

The window over window trick is also possible in doom/2.exe; you do not need a source port for this. Refer to this tutorial (http://www.doomworld.com/tutorials/fx3.php). If you need an example let me know. I have used this trick before and I can point you to one of my maps or create a demo for you.

Thankx, yes I just wanted to make sure eveyone knew I was using PrBOOM so they would not suggest using GzDOOM or something with actual 3D floors and what not.

As for an example, I ended up finding one, thank you very much!
