The white balance in that picture is off. That is "white" text. VT100 
were (as far as I can remember) also available with green and amber, but 
white was definitely most common.

Using a real VT100, or an xterm (or whatever) gives you pretty much the 
same experience.

You cannot play Lunar Lander on a VT100. For that you would need a GT40.
