This is what was behind that password protected "door". My only assumption is that you were intended to index your porn sites here.

Apparently even though I am standing right in front of it I can't operate this "door"...and as you can see dialog boxes are generated entirely from Windows and not from the program.

Here is some evidence of graphical corruption, despite the video card having a hojillion GB of VRAM and being orders of magnitude newer than 2002, so it just goes to show how unbelievably shitty 3DNA really is.

Here is the "Control Pad" for adjusting various options within 3DNA. Apparently there are multiple obnoxious background tracks to choose from. Fortunately you can just turn the speakers off and not be serenaded with that mindless garbage...but isn't the gimmick part of the reason you bought the program?

There are two different "schemes" for controlling movement within 3DNA, selectable here. Of course these aren't customizable...even though it would be dead simple to do that.

There are also hotkeys for various bays and other aspects of 3DNA...although it looks like these are not really configurable either!
