the quiet room
Slow down with one breathing ring and a dimmer that stays where you leave it; put one burden down and leave it down.
the machine shop
All 256 elementary cellular automata, one rule at a time. Pick a rule and watch it run.
A row of cells. Each new row is decided by the three cells above it, and the eight possible neighbourhoods are the eight bits of the rule number. That is the whole machine. Rule 110 can compute anything; rule 0 cannot be bothered.
Rule 110, running from one live cell.
111 110 101 100 011 010 001 000 0 1 1 0 1 1 1 0 rule 110
The eight columns above are the eight neighbourhoods, high to low. Drag the rule slider and watch which bit you just flipped.
