I'm thinking they're not.
Don't get me wrong, I love what Dwell Studio is doing with snakes (and their trellis in particular). I can't wait to see more of the line. I just don't think snakes will ever be as popular in contemporary decorating as birds have been. They're just too... well, snakey.
Elizabeth and James:
There's so much negative symbolism associated with snakes, especially in Judaic and Christian traditions. (Consider Harry Potter and the house of Slytherin.) Snakes freak people out. They give folks the shivers, the heebie jeebies, the willies, if you will. As a result, though gritty nature may be a hot decorating theme right now, no matter how many snails appear in terrariums, no matter how many rats become chefs in the movies, snakes will always be a little too much for many.
