An indoor scene, situated in Pravets, Bulgaria, displays a light brown wooden desk against a plain white wall. On the left side of the desk, a black HP EliteDesk computer tower is horizontally oriented, with a black wired mouse resting on its top surface. To the right of the computer tower, a black HP ProDisplay P200 monitor stands; its screen is off and shows visible smudges. A black wired keyboard is positioned directly in front of the monitor, and various black cables are visible connecting the components and coiled behind the monitor. In the immediate foreground, an open, white spiral-bound notebook lies, displaying handwritten mathematical equations and geometric diagrams in black ink across both visible pages. No individuals or discernible actions are depicted.
