Sydney District Court Judge Peter Zahra cancelled the trial of two men on drugs conspiracy charges after the jury foreperson admitted that four to five jurors had been playing the addictive number sequence game, local media reported. The judge was alerted after some of the jurors were observed writing their notes vertically, rather than horizontally.
The jury members claimed that it helped them pay attention. Sure it did.
I remember constantly doodling when I was in school. But I didn't draw cartoon characters or scenes. Instead I drew tight spirals, zooming closer and farther away. I drew 3d boxes and lines converging and diverging. Doodling didn't help me pay attention to the teacher, but it sure did help keep me from falling asleep!
