The folks at Physalia studio were asked by a company called IdN to produce a little bit of video with a logo. After tossing a few ideas around, they hit upon the concept of projecting the IdN logo inside a falling water droplet. CGI would never get this idea right, so the finished product is the result of stop-motion animation created inside several thousand falling drops of water.
Taking a picture of a falling water droplet was relatively easy; a small drip, a laser pointer and photodiode, and a flash trigger were all that was needed to freeze a drop of water in time. The impressive part of the build is a motion control system for the camera. This system moves the camera along the vertical axis very slowly, capturing one water droplet at a time.
Behind the droplet is a an animation that’s seemingly inspired by a Rorschach test, ending on the IdN logo. The frames for these animations were printed out and placed inside the test chamber/studio upside down to account for the optical effects of a sphere of water.
The end result is a product of over 20,000 pictures taken, all edited down into a single 30-second shot. An amazing amount of work for such a short video but as you can see in the videos below, it’s well worth the effort.
