Dot art, also known as polka dot art, is a style of art where dots are a central element. While many artists have used dots, Yayoi Kusama, a celebrated Japanese artist, has made them her signature.  Kusama's work is often characterized by her repetitive use of dots and her vibrant, psychedelic installations. She began using dots in her art to cope with hallucinations she experienced as a child, which often made her feel as though she was disappearing into a field of polka dots. This led to her famous "infinity nets" and "infinity rooms," where dots seem to multiply endlessly, creating a sense of boundless space and immersion.

Kusama’s art is a testament to the power of a single idea, or in her case, a single dot, to become something monumental. Her work shows students that even the smallest idea can grow into something extraordinary, a perfect message for Dot Day.
