Chrome plays with the potential of contemporary
software and hardware, from generative realtime
graphics and custom smart contracts, to displays
with ever increasing resolution and quality. The
onchain software work responds to screen size
and builds directly on the pixels of the
specific display it runs on.
UTC ). It emerges from a continuous linear motion,
interrupted by a choreography between rhythm and
random. Every channel is offset one additional
second into the future, based on the token id
assigned by the custom smart contract. This
relation becomes visible when multiple channels
are running in a shared space. Compositions
emerge and evolve at various regular intervals,
without ever repeating.
Once per hour the synchronization stops
and all channels act individually,
before they transition back to coordination.
On March 1, 6PM CET , the 128
channels of Chrome can be minted,
in sets of 8 channels (consecutive
token ids), in pairs of 2, or as single
channel .
A 24h pre-sale starts 28 Feb 6PM CET,
for collectors on the allowlist.
A "set" is 8 tokens with consecutive ids and
time offsets. A pair is 2 tokens with
consecutive ids and time offsets. Collectors of
multiple channels can display them together and
see the time difference, the synchronization and
the choreography that emerges between them.
The custom
smart contract
stores the 15kb code of the work on the ethereum
blockchain. It also enables minting sets with
consecutive token ids in a single transaction.
