How can the beauty of light help solve the climate crisis? What does it mean to see the stars at night? And what can we learn from fireflies? These are the questions answered by the enlightening artworks of Dutch artist Daan Roosegaarde. Daan is the founder of the social design lab Studio Roosegaarde, most famous for Spark, organic sustainable fireworks inspired in part by his love of fireflies. Studio Roosegaarde’s immersive, large-scale artworks operate at the intersection of art, design, and engineering and are often poetic and mesmerising and always thought-provoking. WGSN’s executive editorial director Bethan Ryder and Director of Strategic Forecasting Lisa White talk to Daan about his passion for light, something that radiates from global projects, which address the climate crisis and ask how we can learn from nature to create a better tomorrow.
