TurtleArt is an app that lets you make images with your iPad.
The Turtle follows a sequence of commands that you specify by snapping together puzzle
like blocks. The blocks can tell the turtle to draw lines and arcs, draw in different
colors, go to a specific place on the screen, etc. There are also blocks that let you
repeat or name sequences. Other blocks perform arithmetic operations.
The sequence of blocks is a program that describes an image. This kind of programming
is inspired by the LOGO programming language. It was designed to be easy enough for
children and yet powerful enough for people of all ages. TurtleArt focuses on making
images while allowing you to explore geometry and programming.
In the late 1960s Seymour Papert and his colleagues started developing the Logo
programming language. Their idea was that children learn best by making things that
are personally meaningful. The early versions of Logo introduced the Turtle, a
cybernetic creature that responded to commands and established an environment rich in
mathematical thinking. It's 50 years later and those ideas are still powerful and relevant.
We created TurtleArt for making artistic images. Images made with a combination of
math and code. TurtleArt has a small vocabulary. The Turtle only knows about image
making. This makes it a microworld, not a general coding environment like many other
block based systems.
Paula is Co-Founder of the Playful Invention Company. She holds a degree in computer
science from her native Argentina and a graduate degree from the Education and Technology program at Harvard.
She contributed to the design of several coding environments for children such as MicroWorlds, PicoCricket, Scratch, ScratchJr, and LEGO WeDo.
She is a consultant for the Lifelong Kindergarten group at the MIT Media Lab, and for the LEGO company.
Since the late 1970s, Brian Silverman has been involved in the invention of learning
environments for children. His work includes dozens of Logo versions (including LogoWriter & MicroWorlds),
Scratch, LEGO robotics, TurtleArt and the PicoCricket. Brian has been a Consulting Scientist to the MIT Media Lab,
enjoys recreational math, and is a computer scientist and master tinkerer. He once even built
a tic-tac-toe playing computer out of TinkerToys.

of the PicoBlocks programming language, which we used in TurtleArt.
