A graduate of the College of Fine Arts in Bangkok, he has works in many fields, including painting and poetry.

One of his works was a performance art piece involving fake rubber breasts and buttocks and a simulated rape of the entire nation of Thailand.

The group has used his artwork as backgrounds for their demonstration stages, on their T-shirts and propaganda outlets, and Vasan appeared at the rallies to recite poems or perform music.
