Laser Pointer Holograms

This home-page gives enough information to get started and also includes an order form for the photographic plates and chemicals needed to develop the holograms. Also, another page discusses the same techniques and materiels, but comes with some nifty pictures (2-d of course) of the final outcome."

  1. Can I interest you in some holography? by daeley · · Score: 2, Funny

    Man: Is your uh, is your wife interested in....holography, ay? 'Holographs, ay', he asked him knowingly?

    Squire: Holography?

    Man: Snap snap, grin grin, wink wink, nudge nudge, say no more?

    Squire: Laser pointer diodes, eh?

    Man: They could be, they could be taken with diodes. Candid, you know, CANDID holography?

    Squire: No, no I'm afraid we don't have a laser pointer.

  2. Laser pointer projection fun by Jucius+Maximus · · Score: 2, Funny

    Those laser pointers you can get with with switchable tips that cause the device to project different 2D images (by multi-slit-diffraction, I suspect) can be fun. One time I was in a hotel up on the tenth floor and I had just bought one of these toys.

    [Side note: yes, I know this is somewhat off topic, but this thing I'm about to tell you could have amplified effect with 3D projections.]

    I stuck on the tip which projected a 'UFO' image, stepped out onto the balcony and shone it onto the ground. I moved it around and after a few seconds I heard some little girl scream "MOMMY!" so then turned it off. Imagine what you could do with one of these things projecting the right 3D image ... fun!
