Mystery Optics

Last week I was looking through photos on my camera and found this mystery shot. It looked like something I might have photographed but had know idea what it was. Turns out NP had borrowed the camera to take photos of fibre optics - who knew they could be so good looking? Apparently he was trying to demonstrate why it takes so long to repair a fibre optic cable. Not even the craftiest nanna could get this mess under control!
