The University of Adelaide Coat of Arms emblazoned with the universe motto 'Sub Cruce Lumen', meaning 'The light (of learning) under the (Southern) Cross', might indeed carry a hidden message.
Perhaps the symbolic text represented on the feature book is nothing more than artistic scrawl. Or perhaps there is more to it.
Look close and you will see repeating pattern of symbols and form. Perhaps the artist was commissioned to present a deeper message in these mysterious runes. Or going way out on a limb, perhaps some mystical enchantment willed there form into creation
It's probably just artistic scrawl after-all but it sure looks convincing.
