As I’m now able to experience a second childhood (i.e. I’ve carefully curated my daughter’s tastes to match my own) I thought that the new LEGO Mario was interesting.
It’s a LEGO figure that takes two AAA batteries, has bluetooth, a speaker, and an OLED screen in the eyes, mouth, and stomach area.
I think there’s also a motion sensor, and an image sensor on the bottom that can detect colours as well as some form of QR code.
The basic idea is that you build a course for Mario and then as you play the course the figure can detect the coloured bricks, collect coins, and play sound effects.
My daughter likes bouncing it around the room, and on my head, to see where coins are hidden.
