Joke Caimo (they/them/she/her) is an artist exploring how collective energy, intimacy, and physiological rhythms can become forms of communication. Their work creates situations in which people influence one another through breath, pleasure, voice, enthusiasm, and other subtle signals — often amplified by cyborg tools and participatory instruments. Caimo develops hybrid devices such as the Human Organ Instrument (HOI), which translates breath into organ tones and turns groups of participants into a breathing ensemble. With the MOODY®, they make collective enthusiasm visible, highlighting how affect circulates within groups. Their ongoing project visualizing orgasmic rhythms uses buttplug-based sensors to explore pleasure as a relational signal rather than an individual event. Alongside these tools, Caimo organizes collective singing practices such as Koorvorming and the Megaphone-Ensemble, where participants co-regulate through voice, resonance, and shared attention. Voices, bodies, and machines form ecosystems in which communication happens beyond language. They are co-initiator of Samenschool, an artist-run community center and print studio dedicated to collective imagination, experimental learning, and new ways of being together.
