This week's fun Blackbox will overlay your image with drops. These drops can be tinted any color and their size and density can be adjusted. You can make this effect simulate condensation, water droplets, underwater bubbles and more.
Just search for "drops" in the Blackbox browser (Go to File -> Import Blackbox) and start making awesome creations!
