"Artists usually turn to abstraction because they harbour a desire to change the world. By only alluding to natural phenomena, abstract work avoids being parochial and implies universality. O'Brien, who lives in Penwith and is self- taught in art, fell into abstraction as the quickest way to start what he felt strongly needed to be done. That was to create in order to search and thereby to change."    Martin Holman 2021
