I started testing with materials and colors that resemble human skin and flesh qualities, human hair and cast of human body parts.

Later on, the tests became an abstraction and stylization, leaving behind the obvious body casts, and the more cartoonish representations. And started to define the aesthetics based on human skin qualities. 

I decided that was more interesting if the objects would work at different levels and not just at the visual level. Therefore by the experience of the usage of the object, the user could relate to the taboo in a tactile level too.

So at this point the hair, the texture, reliefs and softness of the interface material became in focus.
