Late, great author, Terry Pratchett, likens inspiration to random particles sleeting through space leaving searing, white hot trails across any brain they pass through. I don't often have such 'eureka' moments - I tend to get a slow burn rather than a flash of inspiration. But there is no denying that the strangest things can prompt a new idea. I try to keep my camera handy (not having a camera on my antiquated phone!) but the most important thing is to keep your brain handy.  See what's around you, interesting patterns, shapes and colours crop up in the most unexpected places.

Love the way the paint has weathered to just leave a flash of bright green

Over a barrel - great crackle effect
