A Memocube is a vessel for what a life leaves behind. Written in light and sealed inside fused silica, it is built to remain intact and readable for at least a quarter of a million years. To commission one is a quiet, deliberate act: the choice of what to send forward when everything else has worn away.
One million such Memocubes together form the Tesseract — the pyramid of our age. The DARI Foundation builds it to preserve and carry the record of human creation forward, through the emergence of artificial superintelligence and across deep time.
The Tesseract and Discover Collection have created an edition of eleven Memocubes in the Tesseract’s Inner Core, available only to Members of the Discover Collection community.
The Object
A Memocube is small enough to hold in two hands and heavy enough to feel deliberate. A perfect cube of fused silica with the depth of geological time inside it. The inscription is invisible to the eye: information written in three dimensions within the glass, without breaking its surface. There is enough room inside it for the digitized text of nearly every book ever written.
Each Memocube in this edition carries two records. The first takes most of that space: the civilizational corpus — an immutable record of science and philosophy by which humanity understood itself. The second is the patron’s own, a smaller section inscribed alongside the corpus. Letters, photographs, voices, writings, and even small physical objects sealed inside the silica. One is the legacy of our species. The other is the legacy of a person or family.
Patrons additionally can order up to eleven certified maquettes — empty Memocubes finished as sculptural objects, designed by world-renowned artists — and up to eleven replicas, identical to the original cube and inscribed with the same archive. All maquettes and replicas are numbered in a cryptographic provenance register and may be kept, gifted, or placed across families and institutions. The original Memocube is embedded into the Tesseract.

The Curation
Memocubes are manufactured in collaboration with the laboratory that pioneered data inscription inside fused silica. The writing is performed by focused laser pulses inside the glass, in three dimensions. Each piece is sealed and certified before delivery.
Legacy curation of Discover Collection Memocubes is supported by The Legacy Atelier™, whose work for multigenerational families, family offices, and family foundations has shaped how meaningful legacy collections are curated, preserved, showcased, and built upon.
The Project
The Tesseract has been designed with two purposes beyond preservation. The first: should humanity ever lose continuity with itself — through catastrophe, technological discontinuity, or the simple erosion of millennia — the Tesseract holds the record from which civilization can be reconstructed.
The second: as artificial superintelligence emerges, the Tesseract carries forward, in clear and durable form, the values, languages, and intentions by which humanity has understood itself, so that what comes next has the source material to remain in conversation with what came before.
Patrons participate in both purposes. They hold standing invitations to expeditions to the Tesseract’s final site and to every space probe launch carrying patron’s data from the Tesseract into deep space. Each patron is engraved individually on these probes — a name carried with the archive on its infinite journey through time and space.
The position in Inner Core also confers a voice in how the project is governed: a weighted vote in community decisions, and a standing invitation to the Ethical Commission that oversees what is preserved and how. Patrons attend the Tesseract’s sealing ceremony with VIP access, hold full access to the events programme, and may participate in the broader partner ecosystem, of which Discover Collection is the inaugural member. The patron’s name and personal archive are carried on a dedicated display in the Tesseract Visitors Center.
