Tehran Annual Digital Art Exhibition (TADAEX) was founded in december 2011 to open a new window toward digital art in Iran and to create a serious and independent atmosphere for the enthusiasts and researchers of this field. The generally non-commercial nature of digital art among contemporary art mediums on one hand, and the expensiveness of digital art tools and equipment on the other hand, makes it difficult for the Iranian artists to work and gain experience in this field. Therefore, there might be limited works for display and presentation. Also, the limited academic background and experience need help and management. With all these shortcomings, during the past two periods international artists have been invited to take part in TADAEX for interaction and exchange of experience. This has paved the ground for development and enrichment of Iranian digital art production and presentation. TADAEX, in its third round, has planned to present selection of Iranian and foreign works, hold workshops, lectures, multimedia performances, and introducing international associations and festivals. TADAEX, this time, will provide a chance for digital art artists, specialists, students, and enthusiasts to review the contemporary trend of this art in Iran and in other countries and exchange views and experiences with one another. To realize maximum possible participation of Iranian artists in a completely free and competitive atmosphere, organiz- ers decided to select and display works of Iranian artists through a public invitation for presentation of digital art works. It is hoped that the new achievements of this round of TADAEX would help rapid development of digital art in Iranian visual art field and open new chapters for its growth.
