It was a crt with high-intensity dots and low-intensity dots. The dots
represented the data circulating in the mercury tank memory. It wasn't
long before people discovered it could be used for crude graphics as
well as its intended purpose!
Download an emulator and see it for yourself:

It's a fun machine to write programs for.

The future was never like this!
[...] Edsac (1949) could
display primitive graphics on a 32x16 pixel 2-colour display.
OXO, a Tic-Tac-Toe program by A S Douglas in 1952, displayed
the moves graphically.
But I doubt if anyone in the group has an EDSAC!
Wow! I hadn't heard of this before. What was the display technology?
And by "2-colour" do you really mean it was a color display with
foreground and background, or do you mean it was a black and white
display with full-intensity-on and intensity-off style 'colors'?
