A technical patent diagram of a video game controller unfolds across three detailed views on a dark chalkboard background, rendered in clean white line work that captures the device's ergonomic curves and button layout with engineering precision. The composition stacks the top-down, side, and bottom perspectives vertically, creating a methodical blueprint quality that celebrates the iconic controller's form while maintaining the aesthetic of vintage patent documentation. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
