Anthropology sophomore Van Truong recently combined art and biology in an effort to ace her final exam in December. While most of her college mates used lists and flashcards to memorize stuff, Van used a whiteboard to write out all her notes in the form of Starry Night, Van Gogh’s famous masterpiece. "I knew I had to study for this exam, and I knew I’d be writing on this whiteboard for hours," she said. "So I thought, ’ Wouldn’t it be funny if I did it in a form that people didn’t know how to feel about it?’ "
    So when she got to Smathers Library on the University of Florida’s Gainesville campus, she started to write down all her notes with the words forming a copy of Van Gogh’s famous painting. Three hours later, the masterpiece was complete.
    Truong said that the special technique helped her keep awake during the dull study session, and actually learn more than she normally would have. "I knew if I had to read through a packet of notes, I’d fall asleep," she admitted. "I don’t know if I would’ve lasted three hours just going through notes. I can explain the order of where I placed each word on that Starry Night replica better than a sequence of events in evolutionary history. "
    And the reason she chose Starry Night was because of its composition. She realized that a painting of a person might look detached if made out of words. But she could easily make the sentences look like Van Gogh’s beautiful, wavy brush strokes.
