This guy's work and dedication is truly impressive. He posted a video [1] about his concept of a PCB drone 4 years ago and he and his methods have evolved so much. In addition to his highly specialized knowledge of designing, testing and iterating PCB coils, he also makes comprehensive and interesting videos out of it. I highly recommend checking out his channel.

I saw some product get made that uses the flapping light hologram tech which I'm not sure if he created it first but yeah, pretty cool.

The product is some Tomogachi/Pokemon type thing.
