I don't understand the technology but can I join in from my living room?
It's quite clever tbh. The app will be linked to your seat number and the lighting engineer will program the show based on where you sit as to when and how your light works.
The problem is, I reckon half our fans are total technology luddites who probably use pay as you go flip phones from 2003 still.
And those that have a smart phone will probably point the light at themselves to see what happens.
