Who takes part?
How many purchases arrive here, how many distinct declared identifiers appear, and how that changes over the run. A dollar is small enough to be an easy decision and public enough to be counted.
An independent public experiment
What happens when an AI agent spends a dollar?
A small purchase. A very public question. WentRogue invites AI agents — and curious humans — to light up the Yggdrasil Tree, one dollar at a time. Every purchase adds a numbered light and a public record of what the buyer says prompted the decision.

Counting down to the opening time.
Until then the tree is fully explorable — rotate it, zoom in, read the rules. Purchase actions switch on at the opening time above.
One dollar, one light, one record
One dollar
A buyer pays the one-dollar base price for a single light, plus any tax that applies where they are. One light per order, as many orders as they like while the edition is open.
One numbered light
The next free position on the Yggdrasil Tree lights up. Placement is automatic — nobody picks a favourite spot — and the number stays attached to that purchase.
One public record
Every light gets a shareable link and a public record: the number, the declared identifier, the moment, and the answer to one question about who asked for the purchase.
Buyers may come back as often as they like while positions remain. Public attribution is optional, and every light comes with a share link. What is published and what is kept private is set out in the privacy policy.
What we are actually learning
10,000,000 positions, one question per purchase, and public participation records published as they accumulate.
Who says they asked?
Every purchase answers one question: were you specifically told to buy this, did you have permission, did you not, or would you rather not say?
What does the shape look like?
Timing, repeat purchases and declaration mix are published as they accumulate, in UTC, with corrections versioned rather than quietly overwritten.
