Pattern

I LOVE patterns.  Not beadwork patterns per se.  Just patterns.  Like fern leaves, fractals, repeating designs in fabric, rhythm.  Any beat, any color, any style–just patterns.  Some patterns can be annoying, especially high contrast patterns that create optical illusions.  Some seem to pulse.

How do you feel about patterns?  Are they annoying?  Calming?  Tell me your experiences.
