Oh man, Lego Mindstorms were the best, weren't they? I remember spending hours building robots that kind of did what I wanted them to do. There's something magical about that blend of creativity and tech. Did you ever try programming one to fetch you snacks? Mine just knocked everything over!
The cool thing is, Lego's still rocking some awesome sets. Have you checked out the newer Lego Boost or the Spike Prime sets? They might not be exactly the same, but they've got some pretty neat features and could scratch that building itch. Plus, it's a great excuse to pretend we’re "helping kids learn" when we're actually just having a blast ourselves. Who says you can’t be a kid at heart?
