Steve Zafeiriou (b. 1998, Thessaloniki, GR) is a New Media Artist, Technologist, and Founder of Saphire Labs. His practice investigates how technology can influence, shape, and occasionally distort the ways individuals perceive the external world. By employing generative algorithms, electronic circuits, and interactive installations, he examines human behavior in relation to the illusory qualities of perceived reality, inviting observers to reconsider their assumptions and interpretations.

Nostalgie World started as an art installation and evolved into a storytelling wellness universe.

In 2023, it was awarded People’s Choice at Doncaster Art Fair.
In 2025, I exhibited it again at the MATAROA Awards as a selected emerging artist.

Now I’m expanding the scope and mission of the project, from an installation into a next-generation, immersive storytelling brand.

I’ve just shipped the first digital experience inside Nostalgie World:
The Journey of Reset - A personalized 7-day journaling experience designed to help you reset, reconnect with yourself, and learn to trust your own voice again.
