For the Design Ah! Exhibition, which was held across Japan in 6 locations from 2018 to 2021, aircord led the technical direction and device development for the works "Fast Ah!" and "Slow Ah!" created together with Tomohiro Okazaki, and "Turn the wheel to make a sound”" by perfektron (Ryota Kuwakubo & Reiko Yamaguchi).

Similar to letter “A,” in Japanese “Ah” or “あ” is the first character in the Japanese hiragana alphabet, and represents sounds of surprise and discovery. The exhibition is based on the concept from NHK's educational TV program "Design Ah!” aircord collaborated on 3 of the works in this exhibition: The works "Fast Ah!" and "Slow Ah!" use several small cameras to create a time lapse video that allows for the concept of time to be experienced. The work "Turn the wheel to make a sound" allows guests to learn about power transmission by changing the speed of music through rotating the gear that they put on.
