Izhora is the largest known cellular automation computer, released in 2021 by Yoel Matveyev[1] and based on his own rule FireWorld. It has 256 kilobytes of memory, a 256x128 memory-mapped pixel display and a keyboard driven by a script. Its 32-bit CPU uses a single operation, subtract and branch if zero or negative (SUBLEQ)[2], from which all other operations can be synthesized. Examples include 256-bit factorials, primes and Fibonacci numbers. Tools such as an assembler and emulator are provided for programming it.
