In 1991, Owain won the chair at the National Eisteddfod of Wales at Mold for a poem titled "Awdl Foliant Merch ein Hamserau" (The Girl of Our Times).

[1] His poems have been read on television by actor Rhys Ifans, but the poet himself has declined to be interviewed in the mass media.

[5] Bryn Terfel has performed "Brenin y Ser" (The King of The Stars), which was written by Owain and the composer Robat Arwyn, as was "Pedair Oed", recorded by Côr Rhuthun and Rhys Meirion in 2004.

[8] On 1 July 2013, Owain was appointed the first Wales Manager by Wikimedia UK and Wici Cymru,[9][7] with the objective of expanding Wicipedia Cymraeg [cy] (Welsh Wikipedia).

As part of this programme, the Welsh Assembly contributed financially to the training of new editors.
