Across (Tezos) by Truedrew #1

Across is a single generative art collection that spans 9 chains.

If two pieces of art come from the same algorithm but are minted on different chains, are they one collection or two?

Is each blockchain its own medium? Is "blockchain" the medium? Is code the medium?

There are 10 pieces on each chain. These are Tezos' 10.
