Oh alright, that makes sense. A while back I wanted to make a coffee table and never got around to it so I think the wireless coils are always in the back of my mind. Basically to see if for the fun of it I could make a coffee table for the living room made of wood or mixed materials near designated patterns where essentially from the top it would look normal but if you put your device on any of the designated places it would recognize your device and start charging it. Not a fan of this color/design but basically if you had say this where if done right you could basically get a small charge on any square and potentially even get the magnet to work if done right. While reinforcing it so it doesn't structurally have any issues. Aka coffee table can be used normally, someone can spill something on it, no issues but also near thoughtless charging if anyone is in the living room.

It could even just be all the outside squares, where they lock in the center if the magnet works.
