.fluid, like Light Kinetics, uses the properties of physical phenomena to create compelling interactive displays. However, .fluid rather than using a well known medium like light and giving it novel properties, instead uses the amusing properties of a rather unknown material. Specifically, ,fluid uses the properties of non-Newtonian fluid as the centerpiece of the display. This particular fluid is a shear-thickening fluid, meaning as more force is applied, the more viscous the fluid becomes, thus creating the various shapes. I very much liked this project, and my only complaint is with the presentation somewhat applying that the fluid reacts to music, though it does not, and only reacts to haptic input.
