The Future Nears: Spinning LED Fan Creates Illusion Of A 3-D Hologram

October 12, 2017


This is a video demonstration of a gadget that appears to project 3-D holograms. It's actually just a spinning fan with quickly changing LEDs along its blades though (similar in concept to those bike wheel light kits that play moving graphics, except with much more detailed graphics). Pretty cool, right? Also, where was the Princess Leia animation? You don't make something like this and not include a Princess Leia and R2-D2 animation, I don't care what the copyright laws are.

Keep going for the video but watch to the end, it gets better and better. Also, apparently it would look even better with a camera with a framerate closer to the fan's speed (so you wouldn't see the blade effect like in this video), and even better than that WITH YOUR NAKED EYES. I love your naked eyes. Stare at the sun with me?

Thanks to Clint, who agrees magic is all around us. But mostly in the forest and bogs, because that's where witches live.

    LeadingF supply this.

    I suppose if you got the fan to spin fast enough that you didn't see the gaps in the lighting, this'd be really cool. Until then it's meh.

  • GeneralDisorder

    There's a SmarterEveryDay video about that...

    There probably isn't any gaps, it's just the video capturing at 60fps is playing havoc with the true displayed image.

    Great, now kids everywhere will be wanting one for Christmas.

    The future? This is about the oldest tech in entertainment history. It's a modern zoetrope.

  • Bosun Higgs

    "Persistence of vision" toys of this sort have been on the market for years. And this is hardly "3D." If the camera had been moved during the demonstration, one would easily see that it is a flat plane, like a TV. (Always remember that most cameras are monocular, which inherently opens the way for depth and perspective illusions that do not work with binocular vision.)

  • Wonfis

    Got me thinking; they could do it pseudo-3D with fan blades at different levels.

  • GeneralDisorder

    Yes. I mean, you can use a flat panel TV to make a 3D illusion. And if you distort the picture and use some end-user optics you can really make yourself puke.

    You posted this for the sole purpose of getting me to say it again, didn't you, GW?

    Oooh pretty! *THWACK!*

  • The_Wretched

    It's pretty amazing that all works. Any note on how many fingers it's removed?

  • Bling Nye

    Instructions unclear, penis stuck in fan.

  • The_Wretched

    Who hasn't had that happen?

  • GeneralDisorder

    Only that one time...
