Settle one per session, starting with #1. Each answer goes to the decisions log.
- One word set: dimension / column / kind / lens? option / value?
- Real cube vs mental cube: may a piece show on several faces, and may it be twisted?
- Must faces and positions mean something everywhere (Mosaic)?
- Is a question part of the cube, or only a hint?
- List or grouped when a cube opens?
- Depth: no base case everywhere, or capped per project?
- Three dimensions on a phone: colour, depth slider or small multiples? (Try colour first.)
- Two visual dialects: one system with two themes, or two?
Parked: will people use a nameless colour-only dimension · how a 1×1×1 grows without pressure to fill · zoom on a card or as a gesture · Kitchen as the next real cube · a shared cube component and backend module.
