We just saw this incredibly new reactive foil wall. We don't know what it does yet and as described by Studio Roosegaarde the

Lotus 7.0 is an organic wall made out of smart foils which open while interacting with human behavior. Walking by 'Lotus 7.0' its hundreds of squares unfold themselves in an organic way; creating little see-troughs between private and public. Here physical walls become alive, in a poetic morphing of space and people.

We're interested in the metamorphosis. How does one thing become another? Is it when the light changes? Does it have to be active or can change be passive? It's the question of the effect of parallax when rushing by at 45 miles an hour or the zoetrope.

What do you think?
