Pink, red, and "leaves" of light green anodized aluminum rings -- smooth, cool, and lightweight -- alternate around a yellow and pink center. Gradients of red to pink small rings provide visual interest, while the ring configuration yields multiple fidgeting possibilities. I like to carefully stand mine on its edge when I'm in a long meeting.
The Fugue fidget is the largest one I make, with a diameter of 3.5" (9cm), and is composed of a total of 164 individually-placed rings (54 large and 110 small). As you can imagine, this takes a while to make, but it's really lovely to fidget with when it's done!
