UK iPhone developer Mindbrix has introduced a new drawing app for iPad, iPhone and iPod touch.
Vectoria is billed as a revolutionary app that reinvents Turtle Graphics, with the ability to draw patterns, which can be explored in real time and shared with friends.
"To draw you simply move the pen/turtle forward in a straight line or round in an arc," Mindbrix notes. "To add a corner you rotate the pen before drawing again. Any shape can be built using combinations of these three simple steps."
Each step of the drawing is recorded in sequence and can be edited on the fly, while patterns are made by selecting a group of previous steps and repeating them a number of times
Available from the Apple iTunes App Store, Vectoria costs £2.99 and requires iOS 3.1 or later.
