## Full text

(R, Z, P): rotation, zooming, panning. Map-like interaction can pass parameters this way.
With N people this becomes (R1, Z1, P1) ... (Rn, Zn, Pn).

A network effect here? Inter-device? nC2?

Interaction options

Option 1. Piano. Playing the piano: each key hit is either 1) applied directly to a state, in the traditional way, or 2) applied as an event that triggers an inter-state transition. The result: a kind of 3D collage, a pastiche.

Option 2. A map plus RFID chips, with mobile access. The mobile site should be meaningful and fun on its own, as a mobile site alone, while through sensory, embodied interaction it also affects its surroundings in real time.

Output screens: not explicitly a map, more of a cityscape or collage.
Dynamic? System? Semantic layer? Navigation? Emergence? Activation?
