Cafodd y llythrennau eu dylunio gan Smorgasbord, asiantaeth greadigol Croeso Cymru, a’u gwneud gan Wild Creations, sef y cwmni o Gaerdydd a greodd y ‘Bêl yn y Wal’ yng nghastell Caerdydd ar gyfer Cwpan Rygbi’r Byd yn 2015. Wrth greu’r gair EPIC, fe’i gorchuddiwyd â haenen adlewyrchol a fydd yn adlewyrchu prydferthwch tirwedd Cymru. Treuliodd pedwar o bobl dair wythnos yn adeiladu’r gosodiad, ac mae’r llythrennau’n pwyso 350kg yr un, sy’n gwbl syfrdanol. Bydd angen deg o bobl i’w osod ym mhob lleoliad.
Designed by Visit Wales’s creative agency, Smorgasbord, the EPIC letters have been made by Wild Creations, the Cardiff-based company that created the ‘Ball in the Wall’ at Cardiff castle for the 2015 Rugby World Cup. The EPIC word has been produced with a mirror coating designed to reflect the beauty of the Welsh landscape.  The installation took three weeks and four people to build, and each letter weighs a staggering 350kg. Ten people will be needed to install it in each location.
