But! I can use Blender to pre-render raytraced light into a texture!

And if I make the screen emit the right patterns of light, then the resulting 2 textures should contain enough information for me to mathematically seperate them into 32 individually controllable diffuse lights coming from different parts of the screen.

(The most colourful parts of the textures on the right are parts where the light will change depending on which side of the screen is lit up.)

There'll be another texture for the colours of the computer body, and a very tiny one for the colour and brightness of 32 areas of the screen. The right combination of the 4 textures should produce fairly convincing lighting without giving the GPU a hernia.

Well, honestly not sure how well that will run on a phone. 32 lights requires 35 texture lookups per fragment, which could be a bit much for older phones. Might need a potatophone version that ignores some or all of the colours in the second texture; each one skipped halves the number of lights and almost halves the number of texture lookups.

This whole process should work for both the monochrome display of the B64 desktop computer, and the colour display of the Polybius arcade cabinet. The screen casting full-colour light over the cabinet's joystick & button should be cool.

This'll take a good long while for me to code... I hope it works🤞

Anyway

Sounds like Polybius’ chase theme tbh
