Netherlands based design group Studio Roosengaarde produced this interactive piece of public sculpture titled Marbles. Each of the forms are filled with sensors, LEDs, and speakers which allow them to interact not only with people engaged with them but also with each other.
One of the things I really like about this project is that everything about it lends itself to being really approachable. The scale, materials, and activity of the sculpture all add up to a piece that is, in the words of the designer, something of an “interactive playground”.
