43 In 2002 or before, Zeeshan Ali Khattak and others made a video wall
44 using Gstreamer and Xinerama[1][2]. They called it Video Whale. To
45 run the 4x4 array of monitors, they had 4 computers with 4 video cards
46 in each, and a fifth computer that fed video to the others over the
47 network. Opo was inspired by that project.
49 "Ngā Hau E Whā" is an artwork developed by Leilani Kake for the 2011
50 Auckland Arts Festival, to be shown at Fresh Gallery Otara[3]. It
51 requires four perfectly synchronised video projections.
53 "Opo" was a famous New Zealand dolphin[4].
55 This software was written for Leilani Kake's work, and Opo is a
56 conveniently short and available name for a small New Zealand Video
