In recent years, the intersection of art and technology has given rise to groundbreaking outdoor sculptures controlled by brainwaves. These interactive installations merge neuroscience with creativity, allowing viewers to influence the artwork using their mental activity. Here are some of the most famous examples:

1. "NeuroKnights" by Refik Anadol – Located in Los Angeles, this dynamic sculpture responds to collective brainwave data, creating mesmerizing light patterns based on visitors' mental states.

2. "Mindful Waves" in Tokyo – A large-scale kinetic sculpture that shifts and morphs according to EEG headset readings, offering a surreal experience of mind-over-matter art.

3. "The Thinking Path" (Berlin) – A series of illuminated pillars that change color and intensity based on the brain activity of participants, symbolizing the connection between thought and environment.

4. "Synapse" (New York) – A towering steel structure embedded with LEDs that pulse and flicker in sync with the brainwaves of nearby observers, blending architecture with cognitive science.

These sculptures redefine public art by making it a participatory, neurological experience. As neurotechnology advances, such installations are becoming more sophisticated, pushing the boundaries of how we interact with art.
