This Italian theme park built a chocolate building you can eat

Pavilion commissioned by high-end chocolatier Venchi, at Bologna’s Fico Eataly World – dedicated to Italian cuisine – made of 30,000 chocolates
In true Willy Wonka fashion, designers from the Italian firm of architects, Carlo Ratti Associati (CRA), constructed a building with edible walls.
The pavilion, commissioned by high-end chocolatier Venchi, is made of 30,000 chocolates.

Visitors are free to pick the chocolates off the exterior walls, which measure three metres long and six metres tall.
Inside, there are screens that use facial recognition to measure visitors’ emotions while eating the chocolate.
The system, developed by interaction design studio DotDotDot, analyses each person’s movement of their lips, eyebrows, eyes, nostrils, and forehead. Their face is then projected on the interior walls.
