Device writes on water

Researchers at Akishi­ma Lab­o­ra­to­ries (Mit­sui Zosen), work­ing in con­junc­tion with pro­fes­sor Shigeru Naito of Osa­ka Uni­ver­si­ty, have devel­oped a device that uses waves to draw text and pic­tures on the sur­face of the water. The device 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. The device 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.
