ecaxpr is a tiny, declarative, expressions and predicate logic-based language for elementary cellular automata simulation.

There are a total of only 256 distinct elementary cellular automata. We can refer to each of them via a number from 0 to 255 by representing their state evaluation tables as bits. However, ecaxpr represents their rules not by just a simple number, but as a logical formulae. This provides a distinct way of experimenting with and thinking about these cellular automata.

Here, an expression such as

l == ~(r | t)

***************#*************** 15

becomes...
