If you’ve ever lived in a house with big windows or an office building, you’ve probably seen the distressing sight of a bird colliding with the panes and getting injured or even dying.

Both the university and the Queensland Brain Institute contacted Adam and developed the “zen curtain” to help prevent birds flying into the glass.
