Digital graphics (door entry system) Any ideas??

Hi there folks,

I've got one of the original entry system panels from the movie and it has a digital screen built into it. It's a standard VGA screen that was hooked up to a laptop from what I can work out (I know a lot of the displays were run from iPads, but not this one)

The buttons light up fine and so do the graphics to the side of the buttons, but I really want to get the screen to display the correct style graphics.

I will probably look at using a Raspberry Pi to run the graphics, but does anyone have any idea how to go about creating the correct style of graphics? I'm pretty good at designing stuff, but never done anything animated before. Ever. It's a whole new world for me!!

I can't wait to get it working (somehow) as the entry system to my study.

Many thanks for any help or advice.
