I filmed the video as if playing with shadows, listening to the birds singing on the top of a small hill and feeling the height of the sky from the sound of airplanes passing overhead. I filmed and edited the video in three parts. I came up with the next video from the first edited video and filmed the second video, and then came up with the third video from the second edited video. It took me a year to complete it, but it felt like a year of struggling to write a haiku. I used natural sounds recorded live on location without editing, but it was strange how they somehow matched the edited footage as if they were calculated.
