Crop circles are often though of as eerie or somewhat taboo or discredited. I like to look past the initial judgement to the shape that is being conveyed. I work with the image and expand apon it. I take the shape and bring it into 3d by bending and welding it out of solid aluminum rod. Each one has its own unique "3d sound that reverberates throughout the whole shape when struck.
The examples are approximately 2 1/2' in diameter and made out of 3/8 rod and various aluminum cut outs. If there is one that you like in particular I will do my best to recreate it for you.
