In 2018, Aaron Koblin and Janet Echelman created Unnumbered Sparks, an interactive net sculpture in the sky as a canvas for users to interact with. Aaron Koblin worked on the Google Data Arts Team and Janet Echelman is an artist who specializes in large-scale textiles.
The installation is made of braided fibers stronger than steel. Users act as co-creators as they connect through their phones and can draw with light. Their drawings are projected onto the sculpture. Additionally, every interaction creates a sound.
