Many years ago I took this photo just to try and capture the cool pattern in the snow. I came back to develop it a few weeks later and noticed the heart shapes. I’ve even been able to get a similar photo in recent snow. Amusingly there are enough photos on flickr to warrant a group.
As a further concession to valentine’s day, let me link to a critique of Valentine’s design and the ever lovely Anti Valentines (perhaps I’ll finally give in and use You’ll Do next year).
