To paint on a big sheet of plastic

Let me tackle it a bit bigger, time for a 4 by 5 meter canvas. The nice thing about this is that you can leave it hanging in the wind. Which makes it flutter and all kinds of waves will be visible. Which also gives depth to photos.

 

And not to mention some waving photos. The building behind it is a retirement home. Yes, there were many people who were looking at this fun flowing photo session. Of course you do not see this every day.
