As one of the largest and always one of the best parties of the conference, the Professional and Student Chapters Party hummed Monday night with vibrant conference attendees at On Broadway, one of the largest and most successful clubs in San Diego. The night was bright and pulsing with the energy of another fantastic conference year. Snippets of animated shorts, commercials, and spectacular film clips flashed upon a myriad of screens throughout the venue. Fashion models in exciting new creations wove through the crowds; their designers mingling contently downstairs after the show. The crowd flowed through the several extravagant rooms, winding inevitably up on the spacious dance floor. As our numbers increased, the energy clearly intensified as the night went on. Open to all conference attendees, this event always draws a magnificent crowd of industry professionals and is well known as one of "The" parties to attend. This year the ACM SIGGRAPH Professional and Student Chapters Party celebrates its 20th anniversary.
