norpet is a digital pet with hand-powered logic.

its board (or non-electronic digital screen) consists in a grid of logical operations, one per cell, that you have to follow to bring your pet across its different states of life.

have around two types of beans, like black beans and soy beans, print out the PDF, and follow the instructions.

norpet is a proof-of-concept of beans computing that we developed for the Virtual Pet Jam 2022.

it is based on a 3-bit counter using only NOT and OR gates of one and two inputs respectively.

the state of the changing "pixels" of the pet correspond to the state of the different outputs of the logic gates network.

erm… question… on which cell do you start the loop?

:) great question! once you have set up the three cells at the top (x2, x1, x0), search in the board for the three cells that refer to them, with x2, x1, or x0 inside. from there you’ll be able to find other cells that refer to these in turn.
