SD Card Art Edition

The digital work that draws power.

Every Oracle piece is now available as a physical artwork — on an encrypted SD card. Inserted into a Raspberry Pi 5, the work plays in 4K resolution, with sound and a Hungarian-narrated verse, as an exhibition object, quietly, in an endless loop.

— The concept —

Not a file. Not a print. Not an NFT.

Every piece in the Oracle room is a generative SVG composition — not a still image, but a scene written in text, which the browser rebuilds on every viewing. Until now, this experience was only visible on the website.

The SD Card Art Edition turns this into a physical artwork: the work's source code lives on an encrypted, hardware-paired SD card. The owner places it in a Raspberry Pi 5, and from then on, the work pulses there, in that space, quietly — interrupted every four minutes by a slow Hungarian-voiced verse.

The work cannot be copied: the card only boots on a specific hardware, the system decodes content only into RAM, and every copy is signed by a unique cryptographic key. A duplicate is not the same.

— Two tiers —

Studio or Collector

Studio Edition
50 copies / work
€380 – €510
SanDisk Industrial XI 32GB
Software encryption + hardware pairing

The accessible entry. Industrial-grade SD card, LUKS2 encryption, Z! master-signed certificate. The artwork itself is identical — only the protection layer differs.

Collector Edition
10 copies / work
€1,020 – €1,280
Swissbit PS-45u DP 32GB
Hardware crypto chip + software encryption

The collector tier. Swiss hardware crypto chip physically protecting the encryption key. Anti-clone counter, monotonic boot counter. Limited edition, serial-numbered.

— How it works —

One card, one Pi, one work

01
Choice
You choose an Oracle work and an edition tier. Each work is released in exactly 50 Studio + 10 Collector copies — forever.
02
Delivery
Arrives in a wax-sealed oak box. Contents: engraved SD card, GPG-signed printed certificate, Z! hand-written thank-you note, instruction sheet.
03
Activation
Insert into a Raspberry Pi 5 (sold separately, ~€280). Within ~10 seconds of power-on, the Z! gold seal appears, then the work plays in 4K with sound.
04
Verification
Scan the QR code on the printed certificate to verify authenticity anytime at byzalan.com/studio/verify/. The signature is cryptographically verifiable.
— What's in the box —

Six objects

The SD card
Laser-engraved with Z! logo and serial number. Tamper-evident hologram seal.
Certificate
A4 print, Cormorant Garamond + JetBrains Mono typesetting. GPG-signed ([email protected]), QR code to verifier.
.sig file
Detached GPG signature for the certificate. Anyone can verify with the Z! public key.
Thank-you note
Hand-written by Z! in blue ink, unique to each copy. A few lines on the work, or addressed to the buyer.
Instruction sheet
Hungarian and English, A5 format. Compatible Raspberry Pi models, boot sequence, troubleshooting.
Oak box
Solid oak, sealed with wax. Opening it is irreversible — the first power-on is itself an event.
— What we protect —

Cryptographic proof

A physical artwork must remain authentic for decades. The SD Card Edition uses cryptographic methods to guarantee originality.

ED25519 master signature
Z!'s private key signs every copy uniquely. The public key is openly verifiable. A forged signature is mathematically impossible.
Hash-chained provenance
The card's life events (issuance, signing, sale, transfer) are stored in an immutable chain. Tampering with one event invalidates all subsequent ones.
Hardware pairing
The LUKS2 encryption key is derived from the Pi's CPU serial and the card's factory ID. A simple cloned card in another device produces a black screen.
RAM-only content
The work's source never lives unencrypted on disk. LUKS opens, content copies into the Pi's RAM, then the card is sealed again. On power-off, everything vanishes.
— Anyone can verify —

Public authenticity check

Every copy has a serial (e.g. ORC-0001-03of10). At byzalan.com/studio/verify/, anyone can verify whether a specific card is an authentic Z! release. This is the digital equivalent of a museum's accession number.
