Abstract Thursday: Filter

The abstract challenge this week is to use some kind of filter, either post processing or preferably on the shot.  I'm not sure if the glass stopper to my whisky decanter can be classed as a filter but it does produce some interesting effects; this is a view of the jasmine climbing a trellis at the side of the garden.

I did think of flipping the image but having done so it just looked like a normal photo with an odd border, and this is supposed to be an abstract challenge, after all.
