Wired Logic

Wired Logic can turn a still image like this…

input image

…into an animation like that…

output image

How to run it?

Execute the following command to convert a static image into an animation…

go run $GOPATH/src/ input.gif output.gif

…or draw your own circuit using the Wired Logic Sandbox in your browser.

How does it work?

It scans the image, converts it into a collection of wires, power sources and transistors and runs a simulation on them as long as the state of the simulation does not recur. Then it renders the simulation into the animated gif image.

The rules

Description Example
Wires are all pixels of the color from index 1 to 7 within the palette. wire
A 2x2 pixel square within a wire will make the wire a power source. wire
Wires can cross each other by poking a hole in the middle of their crossing. wire
A transistor gets created by drawing an arbitrarily rotated T-shape and, you guessed it, poking a hole in the middle of their crossing. If a transistor's base gets charged it will stop current from flowing. If not, current will flow but gets reduced by one. wire

The idea

Wired Logic was mainly inspired by Minecraft's Redstone and Wireworld. The first prototype even was a cellular automaton like Wireworld running as a shader within the GPU where each pixel passed its charge - 1 on to its neighbours. But it was slow and impractical so I came up with this implementation.

You can’t perform that action at this time.
