Indigo Monsters is a collaborative project between Vipoo Srivilasa (Thai/Australia), Shin Koyama (Japan) and Pepijn van den Nieuwendijk (The Netherlands).

It began in October 2010 when the three artists first met at the city of blue and white porcelain, Jingdezhen, China.

Using the Surrealist method of exquisite corpse drawing as a way of generating subconscious and unexpected visual imagery, the artists used the international post to send hidden section of drawings between each other. When unfolded the paper revealed a complete, and completely surprising monster artwork.
