DESCRIPTION:I investigate the trade-off between the expected a
 nd the surprising in certain geometric patterns. T
 his work is inspired by Bridget Riley's early Op a
 rt pieces\, "White Discs 2 (1964)" and "Fragment 6
 /9" (1965). I analyse these two works and investig
 ate a range of variants on them. This leads to hyp
 otheses about the perceptual effects in patterns l
 ike these. I first consider adding different types
  of "randomness" to a regular pattern\, and the ef
 fect this has on the generated artwork. I then loo
 k at the balance of the piece: for best aesthetic 
 effect\, there is evidence that the choices made c
 annot be truly random. Finally\, the key hypothesi
 s that arises from the investigations is that ther
 e is an aesthetically interesting range where betw
 een a quarter and a half of a regular pattern is a
 djusted in some way. I report on a perceptual expe
 riment that tests and supports this hypothesis.
