Ballpoint Pen Doodle Image

Create an animated rough ballpoint-pen doodle illustration on lined notebook paper about {{Topic}}. Draw everything in messy, uneven blue-ink lines with visible pen pressure, cross-hatching, and random scribbles, as if drawn absent-mindedly during a boring lecture. Use simple, sketchy forms and an intentionally imperfect hand-drawn look. Add subtle animation such as shaking lines, wiggling elements, motion arrows, dust clouds, and hand-drawn action marks to bring the doodle to life. Maintain a playful, chaotic, hand-sketched feel with a vertical 3:4 aspect ratio, preserving the imperfect notebook aesthetic.
