Interactive Public Art Installation: BUBBLE: A Playful Exploration of Perception in Urban Architecture

In an era where cities are increasingly fast-paced and digitally saturated, urban environments often feel rigid, repetitive, and emotionally distant. Streets become corridors of movement rather than places of experience. The project BUBBLE, designed by Sinan Liu and Xiaotong Liu, challenges this condition through an immersive interactive public art installation that redefines how we perceive architecture and public space.

BUBBLE is not merely an object placed in the city, it is an experiential device. It invites people to pause, reflect, distort, and rediscover their surroundings through color, geometry, and optical transformation.

The Concept: Architecture as a Lens of Perception

The world has become increasingly serious. Routine dominates daily life, and urban architecture often reinforces monotony through repetition and predictability. BUBBLE proposes an alternative way of seeing.

At its core, the installation is inspired by the optical properties of bubbles: reflection, refraction, distortion, and multiplicity. Just as a soap bubble refracts light into iridescent fragments, BUBBLE refracts the city into layered perspectives.

The installation uses:

• Colored glass panels
• Mirrored surfaces
• Polyhedral geometries based on pentagonal intersections
• Modular structural systems

Through these elements, the surrounding urban fabric is fragmented and reassembled into unexpected compositions. Familiar buildings appear unfamiliar. Street life becomes theatrical. Architecture becomes fluid.

This is architecture not as static structure, but as perceptual experience.

Geometry Inspired by Bubble Intersections

The formal system of BUBBLE emerges from the intersection of spherical forms, translated into pentagonal and polyhedral geometries. The designers explored how bubble clusters generate complex yet harmonious spatial relationships.

The installation evolves across scales:

• Small Units: Individual reflective modules acting as perceptual fragments
• Medium Units: Paired polyhedral forms encouraging interaction
• Large Units: Spatial clusters enabling seating and occupation
• XL Units: Immersive structures forming micro-architectural environments

Each module transforms the basic geometry into dynamic groupings. The modularity allows adaptability across different sites depending on human activity, skyline context, and spatial density.

This scalable system strengthens the project’s identity as an interactive public art installation adaptable to diverse urban conditions.

It’s All About How We See

Technology allows us to see and be seen in digital networks. Yet, paradoxically, we often overlook the physical reality around us.

BUBBLE re-centers the act of seeing.

Through transparent and mirrored surfaces, users experience:

• Layered reflections of passersby
• Fragmented skylines
• Overlapping perspectives
• Shifting color filters that tint the city

A reflection on the surface produces distinctive perspectives. In this altered vision, ordinary architectural details, window frames, brick textures, street rhythms, reappear as poetic compositions.

The installation transforms distraction into awareness.

Site Integration: Activating the Urban Fabric

The site plan studies demonstrate how BUBBLE integrates into existing urban conditions rather than competing with them. Positioned within open plazas and pedestrian streets, the installation acts as:

• A visual landmark
• A social catalyst
• A seating structure
• A contemplative retreat

The reflective geometry contrasts with traditional masonry facades, intensifying the dialogue between past and present architecture. Historic buildings multiply across mirrored surfaces, creating an evolving collage of the city.

Instead of dominating the skyline, BUBBLE activates the ground plane, where public life unfolds.

Human Interaction and Play

Unlike monumental architecture that imposes scale, BUBBLE invites occupation.

People can:

• Sit within its angular recesses
• Observe reflections from multiple angles
• Photograph distorted cityscapes
• Experience color-tinted environments

The structure becomes both furniture and sculpture. Its tilted polyhedral body creates dynamic seating zones while its upper reflective shell amplifies verticality.

This fusion of art, architecture, and public engagement reinforces its identity as a contemporary interactive public art installation.

Reflection, Refraction, and Endless Possibilities

Just like a bubble’s surface, the installation suggests infinite possibilities of perception. Each movement of the observer generates a new composition. Each shift in daylight transforms color intensity. Each passerby becomes part of the artwork.

The city becomes fluid.

BUBBLE demonstrates how small-scale architectural interventions can generate powerful spatial transformation. By combining geometry, optics, and human interaction, the project proposes a softer, more playful urban future.

Redefining Urban Architecture Through Experience

BUBBLE is more than a sculptural object, it is a critique of static urban design. It encourages curiosity over routine, participation over passivity, and perception over distraction.

Through its modular polyhedral system and reflective surfaces, the project by Sinan Liu and Xiaotong Liu exemplifies how an interactive public art installation can revitalize architecture and public space simultaneously.

In a world that often feels rigid and overly structured, BUBBLE reminds us that perception is flexible, and architecture can be too.
