Visual Artist Pakan Penn enlightened us with a discussion about his unique painting style - using a palette knife instead of a brush - which results in a textured "3D" effect because of the many paint layers. Also hear about his upbringing in Cambodia and how these memories  influence his work, the great honor he had of having a painting hung in the White House during the 8 years of the Obama Administration and his response to the age-old question "how do you know when a painting is done."
