A challenge from Louise

I didn't take this picture, but I did make this image.

I've often posted on here as to where the line is between a photo and an image, and often it depends on the original picture as to how far you can go before it's one not the other.

Anyway, it was posted by my friend Louise over on Instagram, and these are the patterns she saw on her patio after this morning's frost. There were 4 pictures, all as stunning. They look like leaves have been frozen into the stones,

Isn't nature amazing?
