LLUM 2025 installation in Parc del Poblenou, Barcelona
Vision
Interactive mirrors reflecting collective futures
"Miralls del demà" (Mirrors of Tomorrow) was conceived as an interactive mirror that reflects not just physical appearances, but hopes, dreams, and visions of the future. During the LLUM 2025 festival, we created a space where Barcelona residents could share what they imagine for tomorrow.
The installation combined physical interaction with AI processing to create a unique collective artwork. Each person's future vision was processed, analyzed, and integrated into a growing visual narrative that evolved throughout the festival.
By inviting participants to speak their hopes aloud, the project transformed individual dreams into collective data, creating a living archive of community aspirations during one of Barcelona's most celebrated cultural events.

Architecture
Technical infrastructure and AI processing pipeline
Real-time Processing Pipeline
The technical architecture combined several innovative approaches to capture, process, and visualize spoken futures in real-time. Voice-to-text processing captured spoken visions while AI analysis performed semantic categorization of emerging themes.
- Voice-to-Text Processing: Real-time capture of spoken future visions using advanced speech recognition
- AI Analysis: Semantic analysis and categorization of themes using natural language processing
- Visual Generation: Dynamic visualization of collective hopes and patterns
- Interactive Display: Large-scale public interface for community engagement
Scalable Infrastructure
Built using modern web technologies and deployed on robust cloud infrastructure to handle the festival's high visitor volume. The system processed thousands of interactions while maintaining real-time responsiveness and data integrity.

Insights & Impact
Key learnings and community patterns
Future Vision Patterns
The project revealed fascinating patterns in how people envision their futures, providing insights into collective consciousness and community aspirations:
- Common Themes: Family, environment, technology, and community featured prominently across all age groups
- Language Patterns: Hopes were expressed more concretely and specifically than fears or concerns
- Cultural Diversity: Multiple languages and cultural perspectives enriched the dataset
- Intergenerational Differences: Age groups showed distinct patterns in future concerns and aspirations
Technology as Community Bridge
This project demonstrated how public art installations can serve as platforms for collective reflection and community building, while exploring the intersection of AI, creativity, and human expression. Technology became a medium for deeper human connection rather than a barrier.
Festival Legacy
The installation's success at LLUM 2025 has sparked conversations about the role of interactive art in public spaces and how technology can be used to amplify rather than replace human creativity and community connection.
