    I was completely astounded when I saw the effect. I need to try this myself. I have some kind of "transparent plastic sheet" in my workshop, I need to check which material it actually is.

    I was wondering, though, how the effect would be with "flourescent" plastic, i.e. the kind that "shines" at the edges and can be found, say, in Ponoko's material list. I think I have some leftovers of that, too.

    Bill Beatty did it with glossy opaque plastic, so it doesn't need to be transparent, just shiny.

    Try it Satrek, Great idea! Let us know how it turns out!

    First atempt is a failure, but the material I used turned out to be polystyrene. It's either that or thas I used the tip of a wood scred for scratching...

    I tried it on a CD and it doesn't work--the mirror finish provides too much interference. I'm going to try sanding the back off to see what it looks like.

    you should see what it looks like on a cd. those are cheap like 16cents if you buy 100 of them

    put up a picture of it if you try it :P

    Plexiglass is a brand name for acrylic. Any non-glass window replacement material will probably work as long at it will scratch. Polycarbonate is a little more durable. Even CD covers will work, but they get other cratches very easily.
    Go to your local glass shop and ask if they have small scraps they will give you or sell you at a nominal price. Good luck! Let me know if you have any more questions.

    That's superb ! Really really good, thanks for sharing.

    hahha thatss amazingg dude
