Random Fridays: Prism

This faceted globe of glass looks unassuming, but put in the path of sunlight and it takes on a whole new life. It throws rainbow shapes around the room (as in the feature image), and if I spin the globe I have my own private disco as the colours go whirling around.

As you can imagine, it was difficult to focus on these rays of coloured light. I quite like the “smeared” results, though!
