New magnet technology looks like MAGIC: “Programmable Polymagnets” (youtube.com)

This is fun and informative, but as someone who also played with magnets as a child and adult, alternating poles on one surface is nothing new - most rubberized magnetic strips have created stronger "bonds" using this trick for at least 40 years.

Ok, the latching magnet is pretty cool. I definitely want some cabinets with those as latches.

Wow, that is a very informative and amazing use of 3d printing technology.

I remember seeing another similar polarization control last year, but I don't think it was the same company. Can't recall the name though.. arrg.

Where can I skip to to see amazing polymagnet action ? Am in a room where people are watching telly so can only watch without sound.
