Frequency Domain Mugs
Description: In the mathematical universe, Bigfoot leaves no physical tracks, only a distinct frequency signature. Plotted on a custom-designed application using Fourier Transform epicycles, this royal blue and purple wireframe design is made for electrical engineers, RF specialists, and signal processing professionals.
Description: Rendered on a deep dark background, this artwork presents a damped oscillating signal f(t) transformed into its frequency response F(s), with the integral F(s) = ∫₀^∞ f(t) e^(−st) dt in bold type. Pierre-Simon Laplace (1749–1827) developed the integral transform that bears his name. Engineers use it every day to solve differential equations and analyze circuits, control systems and signals. A gift idea for mechanical engineers, makers and engineering students, and a fitting piece for a workshop, office or study.

Description: Rendered on a deep dark background, this artwork presents four sine harmonics stacked above a square wave rebuilt from their sum, with the series f(x) = 4/π Σ sin(nx)/n for n = 1, 3, 5, 7. In 1822 Joseph Fourier showed that any periodic signal can be written as a sum of sines and cosines. Fourier analysis now underpins audio, image compression, telecommunications and much of modern engineering. Made for engineers, inventors and anyone who loves to understand how things work, it suits a workshop, office or study.
