Ball-Nogues (Studio in Los Angeles) has come up with this creative idea of using colored 30 miles of string in Indianapolis Museum. The string is tightly erected in curvy shaped to make a 3D sculpture inside building. They used a computer-controlled machine to dye & cutting the string. This machine is self build by Ball-Nogues called "nstal-lator 1 with the Variable Information Atomizing Module" can cut & place each length of string in correct size & color.
Overall the design looks cool & catchy, have a look at video below to understand this indoor sculpture beauty.
