you can make a computer out of ANYTHING that has different states.
as a kid i make a biological computer that sensed the time of day using a change in color caused by ants fleeing the sunlight that was concentrated by my brothers fishbowl, the side of the ant farm closest to my mums work desk would suddenly be VERY dark with black ants, so she knew it was time to collect me and my brother from school.
when my brothers fish died the ants stopped migrating, so i my mum didn't have the weird visual change causing her to collect me and my brother, which was when we realized what was going on with the ants, we moved them off the window sill and things improved for the ants, but my biological time computing device was ruined.
