Antograph (or Myrmegraph)
Touch the screen and the “Antograph” will release a string of ants from your fingers. They follow the movement because an invisible chemical track is “left” on the fingers’ way. “Antograph” is a combination of drawing, animation, art, science, and game. One can touch the bottom of the screen to call the tool bar, then change the size, erase, and share on the Facebook or by email.
