SparKubes are a set of stand-alone tangible objects that are corded with simple behaviors and do not require additional instrumentation or setup. This overcomes a variety of issues such as setting up network connection and instrumentation of the environment as long as a SparKube sees another, it “works”. SparKubes can be used to create a variety of low resolution tangible widgets that can control different appliances, e.g. an application on a nearby computer, wall-sized display or mobile device. The nature of the hardware implementation of SparKubes enables a set of seamless interactions between both computational devices and cubes.
