More than 30 years ago we were cleaning up our shop where I worked and they were tossing a bunch of things and out. I saw a unique looking prism. I decided to save it and show the kids what a prism looked like. Fast forward 30 years.....A few days ago I refound it in some junk and decided to make a tree ornament out of it.  This is what I came up with. The biggest problem was how to mount the hook. I ended up using some spring steel and drilled two holes up under the notches. 

 Not traditional, odd and very unique. The overhead picture shows the prism more clearly

That's really cool, Ron! Bet it will make neat light patterns when the sun shines on it.

I Love it Ron, great job and nice re-find!

I love how you are always getting ready for Christmas, all year long!

Now if he could ever give one away. That is one unique use of what you have.

I like it.  Get a light shining on it.  Little rainbows everywhere.
