A whimsical cartoon unicorn with green hair and round glasses holds a pointer stick aloft against a black background covered in mathematical equations, geometric shapes, and scientific symbols rendered in white chalk-like lines. The composition merges playful character illustration with academic visual language, creating a humorous statement about proving the impossible through rigorous logic. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
