Examples

“Spacefiller patterns might possibly even be within reach⟳ of current search⟳ programs; these would have⟳ much more predictable (and higher) growth rates from the start⟳.”

“Other things that can be built (I see⟳ no reason⟳ why not) are a self-replicator, quadratically growing spacefiller, programmable computer/constructor, self-growing prime number⟳ sieve.”
