Write your name upon the water

According to a post on Pink Tentacle, Japanese researchers have prototyped up a device that forms letters on water...

The device, called AMOEBA (Advanced Multiple Organized Experimental Basin), consists of 50 water wave generators encircling a cylindrical tank 1.6 meters in diameter and 30 cm deep (about the size of a backyard kiddie pool). The wave generators move up and down in controlled motions to simultaneously produce a number of cylindrical waves that act as pixels. The pixels, which measure 10 cm in diameter and 4 cm in height, are combined to form lines and shapes. AMOEBA is capable of spelling out the entire roman alphabet, as well as some simple kanji characters. Each letter or picture remains on the water surface only for a moment, but they can be produced in succession on the surface every 3 seconds.

As you might expect, the first application of this technology will be in resorts and amusement parks.

I wonder what would happen if you replaced the water with a very viscous fluid? Would each letter linger longer?
