Feedback Loop Posters and Art Prints

Description: A humorous cartoon shows a bear wearing a beanie standing over a person lying on the ground with their hand on their chin. Text above reads "NATURE'S UNFILTERED FEEDBACK LOOP" and below reads "STAYING CURIOUS, STAYING CURIOUS, REMAINING CALM, AND OTHER UNHELPFUL ADVICE". A backpack and snacks are scattered around the person.

Description: Rendered on a deep dark background, this artwork presents a homeostasis loop of sensor, control center and effector around a 37 °C set point. The French physiologist Claude Bernard (1813–1878) founded experimental medicine and introduced the idea of the milieu intérieur: the stability of the internal environment is the condition of free and independent life. Made for doctors, nurses, medical students and everyone who works in healthcare, it suits a clinic, consulting room, study or student room.

Description: A smartphone explodes into shattered glass beneath the bold message “Destroy the Short-Term Dopamine Feedback Loop.” The heart notification icon, smoke clouds, lightning shapes, and distressed block typography create an intense visual critique of digital addiction and instant gratification. Bright yellow, red, blue, cream, and black amplify the high-impact comic style while emphasizing dopamine detox, screen-time awareness, attention control, social media burnout, and breaking compulsive habits.

Description: A scientific diagram showing a closed-loop control system with blocks labeled C, P, and F. Arrows indicate signal flow from inputs r and y to outputs e, u, and y. Below the diagram are two identical equations for the transfer function H(s) = y(s)/r(s) = C(s)P(s) / (1 + C(s)P(s)F(s)).
