In 2008, visual artist Jan Willem Campmans encountered a frustrating problem: waiting for the paint on his canvases to dry. For someone with mild ADHD, this was particularly challenging.
Seeking an alternative, Campmans explored how to convey his painting process using projection and computer technology, essentially finding a way to paint on canvas without using physical paint. This exploration became the foundation for light drawing/painting.
Collaborating with creative coder Tim Walther, Campmans developed the Happytron—a simplified application that allows intuitive light manipulation via a tablet, computer, and projector. Initially designed for solo use, the Happytron evolved to support multiple creators simultaneously. What began as an artistic solution has now proven itself as a versatile live medium, used at festivals, events, workshops, and by professional artists.

The Happytron originated from an artistic necessity to innovate and adapt. Its ability to create light-based artwork intuitively has made it an essential tool in live art performances and collaborative creative spaces. The software has expanded beyond its initial purpose, finding applications in interactive events and artistic education.
The Happytron allows artists to “paint” with light by connecting a tablet to a projector via a computer. This system supports real-time, intuitive creations that can be manipulated solo or collaboratively. By simplifying the process of light drawing, the Happytron enables both professional artists and beginners to engage in the creative process.
Combining tablet interfaces, projection mapping, and collaborative design, the Happytron has become a widely used tool for artistic expression. Its applications range from live performances to educational workshops, fostering co-creation and breaking traditional barriers between artist and audience.
