Transparent Surfaces: Paint Hanging in Mid-Air?

Paint drops and marks hanging in mid-air? Intrigued by this idea and challenged to work with new surfaces (not canvas), I tried painting on DuraLar (a clear poly that accepts wet media). Mixed results, some interesting effects, and many possibilities... but it is uncompromising! One can't photograph transparency, so you'll need to imagine the background to be clear (24"x19").
