I’m on holiday (‘holiday’) next week, and I’ll be unwinding in part by staring at and spinning the cute wee 3D dioramas of Tiny Lands. Released today, it’s a digital version of that classic activity sheet puzzle: spotting the differences between two near-identical scenes. With your screen split down the middle, the two versions will zoom and spin and rotate in harmony while you check patterns on fish, scrutinise crowds of people, and count rocks. It’s cheap and it’s nice, and that’s enough for me.
