In this art project, the ephemeral and intangible aspects of human's communication are represented by soap-bubble. The shapeless, intangible, and insubstantial speech - once the speech is shouted out through speaker's mouth it disappears unless someone hears it immediately, or even it is heard, the message will be forgotten as time goes - is transferred to a semi-tangible yet still fleeting bubble. The bubble machine that we created provides person-to-person and person-to-space interaction. The machine has a iris mechanism that varies its outlet size reacting to the participant's speech pattern as if it tries to talk something. Once the participant pauses, the machine blows out various sizes of bubble. The floating bubble represents the subtle state of a message from interpersonal communications that lies in the middle of real and digital world. Also, it creates a certain delay until it pops, which is a metaphor of our behavior that we often delay to send out text-messages through chatting apps. We believe that anyone can be an artist. By open sourcing the details of fabrication process and materials, we want to encourage people to build the machine, interact with it at any locations, and use and modify it as a art tool for realizing their own ideas whether it is for art or not.
