Artist Commentary: "It is the life of the crystal, the architect of the flake, the fire of the frost, the soul of the sunbeam. This crisp winter air is full of it." --John Burroughs Frosty ice crystals form on my office window on a very cold January winter morning in Milwaukee. They are beautiful for sure, but it has to be quite frigid for these to grow. Plus, your windows need to be a bit drafty. Oh well, the things we sacrifice for our art.
