The Bencini Comet is pretty basic, but the emphasis is pretty, it's Italian after all. As the image rotates it will reveal the twin red windows, necessary as the camera takes portrait format images, rather than square. Also visible is the sole shutter control that lifts to control instant or B settings. The heavy fluting around the lens barrel looks as though it should do something, but it's purely decorative.

Start the image spinning by putting your cursor over the "Spin" side of the image, you can pause the animation in any position by touching the "Pause" side.
