Look for ice crystals on your windows too. You won't even have to go outside! One year, I used a star filter on my lens and tried to catch the water drops from an icicle hanging off my roof with the sunlight behind it. I finally caught one, but it took a lot of patience. I didn't have to go outside for that one either.
I recently photographed some branches growing into the water. It has an interesting reflection too. I call it Ice Fingers.
A short while later, I photographed this simple reflection of the sun at sunset, like molten gold.
Feel free to post your own ice picture.
