Alexander Chen is an artist at Google who is most well known for his personal work combining music and visualization techniques. At Google, he lead projects like the Chrome Music Lab and A.I machine learning experiments. I think the best way to understand Alexander Chen is to delve into some of his work. One of his the visualizations is for a Beach Boys song. He uses circles and colors to communicate complex auditory ideas. His code works by drawing circles for each note of the song; distinguishing a relationship between circumference of a circular surface and pitch. While this project was fascinating, I was most intrigued by his visualizations with the MTA. I thought his combination of sound with movement patterns was well done. In visualizing MTA patterns and hearing the intersections, it gave me a lot of insight.
