- is it possible to read out the state of a flipdot display?
with a small amount of additional memory the display could hold the game state and you could manually flip the dots to input the cells.
by hidroto - I was really hoping for mechanical clicking and movement.
Also for a glider gun.

- > The switches are around $3 a piece
$3*17*17 = $867 - ouch!
by Retr0id - I’ve always wanted to do something similar, but with screen printed capacitive sensors on a pcb with a matching led in each sensor.
Much more scalable in cost.

- There's probably a way of making these switches for less, if you're willing to trade money for toil and strife. Wind up toys have a very long roll of "wind up spring". 3D print a jig to bend a short piece of that into shape. Use somewhat translucent filament to print the switch. Or use a diffuser/matte thingy from a LCD monitor. I don't know. It'll probably be more expensive in the end but you'll feel good that you did it.
- Cool! This is about an interactive display but initially I thought someone might have managed to make GOL into a physical automaton! Cells could physically sense neighbouring cell states and change their own states.. might still need a global clock to get coherent GOL behaviour but I think that would be fascinating! Also GOL (2,3/3) is only one out of about 1024 possible 2d totalistic CA rules, some of the others have interesting behaviours too and would be fun to be able to explore in the real world :)by danwills
