Abstract Thursday 44 Black and White...

...with a dash or two.  I had some difficulty with this one: firstly, I've only just managed to get a dash  really, unless you can count the greyish parts as dash two.
Secondly, I do find that some B/W abstract images look disturbingly like the visual disturbances that I experience at the onset of a migraine attack.  My first attempts with this did actually make me feel a bit queasy to be honest, but I managed to do a bit of 'swirling' in PS and I feel reasonably comfortable with the result!

Many thanks as always to Youoregon1 who created this challenge and has now refined it by setting us themes on some weeks.
