Lego salt and pepper set (£5)
Lego Mindstorms EV3 (£300)
We've already featured the Mindstorms set in our Christmas Gift Guide for makers, but it bears repeating – this awesome set comes complete with a programmable EV3 brick that can be controlled over Bluetooth using the Mindstorms iOS or Android app.
You can use it to build one of three robot creations out of the box, or let your imagination run wild – the EV3 brick features an ARM 9 processor running a Linux-based OS, USB, Wi-Fi and Bluetooth connectivity, and can be hooked up to an array of sensors.
Lego Architecture: UN Headquarters (£50)
Lego for grown-ups, this kit shuns the smiling minifigures in favour of a serious architectural build based on the modernist United Nations headquarters, as designed by Le Corbusier and Oscar Niemeyer.
Build it, then stick it on a shelf in your study and nod sagely at it while stroking your chin.
