Technical Theatre

I've worked on a number of theatrical events - musicals, concerts, discos, presentations, and dance shows. Although I've always focussed on VFX, I enjoy stepping in to mix sound, improvise lighting, build set and rig equipment. Between cues, I always find time to document the event, for publicity and nostalgia alike. Visit my LinkedIn profile to see the full list of projects.



The aim of my final university project was to satisfy a long-term interest in cue light systems by building a complete solution that gives theatre crews as much freedom as possible post-pandemic.

CloudCue is a hybrid solution, combining the flexibility of a web-based controller with the durability of hardware outstations. The project included PCB design, enclosure design, 3D printing and both C and JavaScript code.

The project achieved an A1 result in all aspects.
