I have a small water-filled glass prism hanging in the back window.
It's like this:

When the sun is shining through that window it casts rainbows on the
floor. I have it hanging from some very fine fishing twine... I turn
it so it swirls and casts light like a disco ball. LOL

My cat Persia *loved( to chase those rainbows! I don't know what she
could actually *see* in the light spectrum but she loved chasing the
rainbows.

Buffy couldn't care less. She also looked at me like I was nuts when I
tried to interest her in a laser pointer. She can see those things, she
just doesn't care. Give her a golf ball, she's all over that!
