Be aware of what is normal to you.The aperture is a device that the amount of light admitted. Depending on how bright the incoming light is, the pupil grows or narrower, much like adjustable aperture of a camera. Visually and functionally they are very similar.
I think aperture have fit in nicely with Uncanny concept. I want to make a eerie and funny product that had long been unconsciously a part of us.
//Aperture In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture of an optical system is the opening that determines the cone angle of a bundle of rays that come to a focus in the image plane. The aperture determines howcollimated the admitted rays are, which is of great importance for the appearance at the image plane. If an aperture is narrow, then highly collimated rays are admitted, resulting in a sharp focus at the image plane. If an aperture is wide, then uncollimated rays are admitted, resulting in a sharp focus only for rays with a certain focal length. This means that a wide aperture results in an image that is sharp around what the lens is focusing on and blurred otherwise. The aperture also determines how many of the incoming rays are actually admitted and thus how much light reaches the image plane (the narrower the aperture, the darker the image for a given exposure time). In the human eye, the pupil is the aperture.
