Bridget Riley never ceases to amaze. Throughout her career, the visionary artist has continually challenged the ways we see and understand the world around us. Now, aged 90, she has no intention of stopping - and says she's still learning from the mistakes of her past.
In an exclusive interview with BBC Newsnight, Riley, who is one of the UK's most renowned artists, described herself as a sort of creative sociologist.
"I held a mirror up to human nature and reported faithfully," she tells Kirsty Wark.
Art has contributed to her own understanding of the world, too. Artists have "borne witness" to society's "changing circumstances and events, to horrors and as well as to wonder," she says.
And as one of the most significant artists of the 20th and 21st century, Riley says she hopes her work has made a contribution to "order, stability and the joy of living."
