Diffraction grating $$$

[Flaminpyro]

Howdy all well I'm looking for some diffraction grating that shows a dollar sign when a laser is shown through it, any one that knows the whereabouts of such material please give me a PM or post it here, Thanks

How soon do you need it?

I think I have one. Though its 120 miles away.

Jeff,
Do you just want one or are you looking for a large amount of them? I think I have a tiny one still in the cap from a keychain laser. If you want it (and I can find it), it's yours.

I have one! If no one else in the US has one, you can have this.

I used a 300mW laser for this, so that's why there's such a bad splash.
