A problem I sometimes have when building with LEGO is that I think too much. Not about life in general – I have a slot in my schedule for existential crises about the struggles of modern life already. What I mean is when I started building something for Marchikoma (the LEGO think tank-themed month), I was thinking about the practicalities of what I was going to build. Will it be armed? Should the legs be armoured? How many will it have, for that matter? And what will I do for the head? Well, for that last one, I came across some smiley faces from a Dots expansion pack. And suddenly, my only criteria became ‘smiley face and big gun’ – which was much more enjoyable to make. Sometimes, it’s better to turn down the brain and let a silly idea lead the way!
