Bridget Riley: Gwahaniaeth rhwng fersiynau

Wrth siarad am ei chelf mewn ffilm dywedodd Riley:

<blockquote>''Mae rhythm ac ail-adrodd wrth wraidd symudiad. Maen nhw'n creu sefyllfa ble tu mewn iddo mae ffurfiau syml, elfennol yn dechrau gweithio'n weledol. Trwy eu casglu ac yn eu hail-adrodd, maent yn dod yn fwy amlwg. Mae ail-adrodd yn dod yn fath o 'ampliffyer' ar gyfer digwyddiadau gweledol sy'n brin i'w gweld ar ben eu hunain. Ond i wneud y ffurfiau elfennol yma cyflawni eu hegni gweledol, mae rhaid iddynt anadlu, fel petai – i agor ac i gau, neu i dynhau ac wedyn ymlacio. Mae rhythm sy'n byw'n gorfod newid cyflymdra a theimlad sut mae'r cyflymdra gweledol yn lledu ac yn crynhoi – weithiau i fynd yn araf ac weithiau’n sydyn. Mae rhaid i'r holl beth fyw.'' <ref> http://painters-table.com/blog/bridget-riley-repetition-rhythm-learning-look-video#.VBGwA-fakVk Bridge Riley yn siarad am ei chelf: "Rhythm and repetition are at the root of movement. They create a situation within which the most simple basic forms start to become visually active. By massing them and repeating them, they become more fully present. Repetition acts as a sort of amplifier for visual events which seen singly would hardly be visible. But to make these basic forms release the full visual energy within them, they have to breathe, as it were - to open and close, or to tighten up and then relax. A rhythm that's alive has to do with changing pace and feeling how the visual speed can expand and contract - sometimes go slower and sometimes go faster. The whole thing must live."</ref></blockquote>
