It reacts to the users stepping on it: every time a panel is activated, it would be light up and make a piano sound. When it is not being used, it would have a few pre-established animation that would be fun to look at.

Tango Triangle interactions


The Triangle Tango is a public intervention designed for the annual International Summer Festival organized by Life Hub @ Daning in their privately-owned public space within their open-air Retail Street.




Life Hub @ Daning, a 250,000 sqm mixed use development with 110,000 sqm shopping mall, is one of the hottest shopping centers in Shanghai, due to its condition of open-air retail street.





From the very beginning the marketing team of Life Hub @ Daning insisted on creating something INTERACTIVE. Something unexpected beyond any typical decorative installation, that would attract kids and adults alike to come and use it, rather than pass by and observe it.

An intervention that, by itself, would turn a circulation area into a “SPACE” to stop and stay, where their customers could bring their kids and families and spend some quality time interacting with other kids and families.

The proposal could not block the visibility of storefronts around it, therefore our approach was to embed an interactive activity at the floor level. That decision led us to an installation where people should engage by stepping with their feet.

For this project we teamed up with the Shanghai-based American engineer and interactive designer Maciej Dudek, from Squiggle Labs, to generate responsive feature.

Based on new generation dancing games, we created a lighting & musical responsive platform reacting to people’s steps onto the triangular panels.

Capacitive sensors placed underneath the glass would feel the electromagnetic field and trigger a light blink and a musical piano tone every time someone would step on it.

Visually designed as a fractal combination of equilateral triangles, it also counts with a graphic design based on interesting patterns within each triangle seeking for a visual impact as an attractor mode whenever nobody was stepping on it.





The monochromatic treatment, with shades of yellow, was extended on the floor beyond the platform to enhance his visual impact.

Painted Scape

Product definition

The Painted Scape is a 2d architectural configuration, which is painted and/or coated to cover a significant area of an existing urban scape. This architectural configuration only intervenes – whether vertically or horizontally - on the surface of the space.
The interaction takes place in the interface between the user and the painted surfaces - vertical or horizontal - in which the users finds information, signals, functional areas and spaces.
The main objective of the painted scape is to call attention to the existing space, inject it with a unique identity, and highlight spatial functions with 2d aesthetics. Through these actions, this intervention makes a formerly unremarkable space an attraction for users and customers.
