kali challenged me to "use rear curtain / slow sync flash with icm or a moving subject this week, for a mix of blur and sharpness." I practiced with the cats playing with some cat toys. The lights are a rotating Christmas light. I was really surprised at how well this works! I'm not sure if I'll get another chance to try this before the challenge ends, and I haven't yet thought of another subject and composition, so I thought I'd best upload one of the cats before I run out of time.
