This section has two collections of samples. The first group has samples to help you get started
with programming in TurtleArt. Each of these samples has a small snippet of code illustrating some block
or some related set of blocks.
The second group showcases 3 simple art projects. These projects are not just to be looked at and studied. You can modify them, rework them, remix them, in any way you can imagine.
To copy a project, just drag the image to your desktop. Then drag the image from the desktop to
Getting Started: Forward, Right, Arc, and Repeat
You make images in TurtleArt by combining blocks into stacks. Sometimes one stack, sometimes more.
This section shows some simple stacks and the images that they produce.
draws a line. Then back 200
retraces that line and brings you back to the starting point.
Repeat the line 10 times with right 36
This makes a star with the lines evenly spaced. The total amount of turning is 10*36=360 degrees,
the number of degrees in a circle.
draws a line. back 200
retraces most of it.
The Turtle doesn't quite get back to its starting point.
Each line starts at a different position than the previous one.
You can name stacks. Pull out an empty hat block (the round yellow one).
Click on it and type in a name. A new block to use that stack will appear in the blocks palette.
In this sample, the square
block isn't there when you start.
It only appears after you have pulled out a hat and named it square
You can make dashed lines with pen up
and pen down
An arc is a part of a circle. There are two inputs to the arc
block: radius and angle.
The radius is the size of the circle. The angle is how much of the circle to draw. An angle of 360 draws the whole circle.
Once you have an interesting element you can "spin" the element with a repeat
and a right
In this case, the element is a double wave with each of the waves made with two arc
store in box1
lets you save a number. box1
recalls that number.
You can use the boxes to make images that have repetiton with variation.
can be used to create a succession of lines of increasing length.
Put an angle between these lines and you get a square spiral.
You can fill areas with start fill
and end fill
. The blocks between start fill
and end fill
define the area to be filled.
Some randomness and some arithmetic lets you position elements. The element here is a dot made by forward 0
Creating Art with TurtleArt
These samples illustrate some of the techniques for making art with TurtleArt.
You can see the code in each sample by following the instructions for copying a project
that appear near the start of this section.
to position elements. This image use the star element twice.
This image uses a similar star element of the above example, and a dot element. Use set pensize
and set shade
to create radial gradients.
to position and / or rotate elements, and to determine their size as well.
