Noise gradients mixed with pixelated information from a human face (iPhone Self-Portrait of Myself Weeping), 2019. 
These images are two dimensional representations of continuous time vector relationships based on a capture of a human face. In other words they can be printed as objects and/or experienced in VR as dimensional realities. 

“The original meaning of “noise” was “unwanted signal”; unwanted electrical fluctuations in signals received by AM radios caused audible acoustic noise (“static”). By analogy, unwanted electrical fluctuations are also called “noise”.[1] [2]

Image noise can range from almost imperceptible specks on a digital photograph taken in good light, to optical and radioastronomical images that are almost entirely noise, from which a small amount of information can be derived by sophisticated processing. Such a noise level would be unacceptable in a photograph since it would be impossible even to determine the subject.”–Wikipedia

noise
  1. Various sounds, usually unwanted or unpleasant.
    He knew that it was trash day, when the garbage collectors made all the noise.
  2. Sound or signal generated by random fluctuations.
  3. (technology) Unwanted part of a signal. (Signal to noise ratio)
  4. (genetics) The measured level of variation in gene expression among cells, regardless of source, within a supposedly identical population.
  5. Rumour or complaint.
    The problems with the new computer system are causing a lot of noise at Head Office.
gradient
  1. slope or incline.
  2. rate of inclination or declination of a slope.
  3. (calculus) Of a function y = f(x) or the graph of such a function, the rate of change of y with respect to x
    that is, the amount by which y changes for a certain (often unit) change in x
    equivalently, the inclination to the X axis of the tangent to the curve of the graph.
  4. (sciences) The rate at which a physical quantity increases or decreases relative to change in a given variable, especially distance.
  5. (mathematical analysis) A differential operator that maps each point of a scalar field to a vector pointed in the direction of the greatest rate of change of the scalar. Notation for a scalar field φ: ∇φ
  6. gradual change in color. A color gradientgradation.

 

A continuous signal or a continuous-time signal is a varying quantity (a signal) whose domain, which is often time, is a continuum (e.g., a connected interval of the reals). That is, the function’s domain is an uncountable set. The function itself need not be continuous. To contrast, a discrete time signal has a countable domain, like the natural numbers.
A signal of continuous amplitude and time is known as a continuous-time signal or an analog signal. This (a signal) will have some value at every instant of time. The electrical signals derived in proportion with the physical quantities such as temperature, pressure, sound etc. are generally continuous signals. Other examples of continuous signals are sine wave, cosine wave, triangular wave etc.
