Blur

This is my first attempt at the experimental photography challenge.  The "filter" was a clear plastic bag which I found in a drawer in the kitchen, I cut it down in size, set the camera on a tripod, and then held the plastic in front of the lens as I fired the shutter.  I think the plastic was too thick, so I will look for some thinner plastic for when I try this again, and I will be on the lookout for other materials as well.  I wasn't sure whether yesterday's photograph was suitable for the challenge, does rain count as a filter?
