The NTT Intercommunication Center's annual kids' program this year aims to inspire children to challenge and question the world during their summer vacation. Presented as a factory-themed modern-art show, the exhibition includes interactive installations with elements of surprise.

One installation allows participants to use light to draw images in the air with "clap light" hand gloves, while another surrounds viewers with a projection of animation across walls. Kids can create their own designs using Plarail toy train tracks, while other works involve shadows, knitting and pinhole cameras; July 19-Aug. 31.
