The Lantern Suite / Behind the design
Dual Harmony
Switching between two rules with a steady, flexible mind
Dual Harmony is a task-switching exercise: a card lands in the Garden, where players sort by symbol, or the Court, where they sort by number. Its reflections frame that flexibility as a strength that people who live between cultures use every day.
What players see
The science
Cognitive flexibility. Shifting between rules and roles helps when moving from class to a work crew, between family and peer expectations, and into new systems after release.
Task-switching research measures the "switch cost," the extra time people need when the rule changes. Dual Harmony reports each player's own switch cost.
Monsell, 2003, "Task switching," Trends in Cognitive SciencesRogers and Monsell used a stimulus's screen position to signal which task to do. The game's garden-or-court placement follows that cue-by-location design.
Rogers & Monsell, 1995, "Costs of a predictable switch between simple cognitive tasks," Journal of Experimental Psychology: GeneralBicultural individuals shift cultural frames in response to cues, a finding that informs the game's framing of flexibility as a bicultural strength.

Culture players carry with them
Players learn about the Four Gentlemen of East Asian ink painting, why bamboo and chrysanthemum are admired, and the tools and brushwork painters use. Notes name the tradition in China, Korea, Japan and Vietnam, where it is still taught today.
- The Four GentlemenIn East Asian ink painting, plum blossom, orchid, bamboo and chrysanthemum are called the Four Gentlemen. Each is linked to a season: plum to winter, orchid to spring, bamboo to summer, chrysanthemum to autumn.
- Four TreasuresInk painters use four basic tools, called the Four Treasures of the Study: a brush, an ink stick, an inkstone for grinding the ink with water, and paper.
- Learning With BambooMany beginners learn brushwork by painting bamboo: long strokes for stalks, short ones for joints, quick ones for leaves. An old Chinese painting guide, the Mustard Seed Garden Manual, has a whole section on bamboo.
Culture notes as they appear in the game, between levels and on the title screen.
