Artists were selling their designer birdhouses at Christmas time. This one is made with tinker toys. Remember them?
Here is one with dominoes.
Not sure what this one means. But it reminds me of Edvard Munch's painting "The Scream."
“I will pluck the green from the treetops, where wild birds nest and sing, and in the weaving I will ensnare a song. And when Sorrow is my guest, I will wear a gown made of the cold, gray mist.”
