You can use the pen tool in EToys to create drawings.

Start by creating yourself a little drawing robot like this .  Name it Bot.  (Hint: Give it a nose so that you can see which direction it is pointing in!)

Open a viewer for bot.  Then add in a pen category pane.  Set Pen Down to be True.

Select the pen size and colour you want. 

Create and run the following script:

Now, click on the useful box at the top of the script window.  Change Repeat to 4, and drag the forward and turn tiles into the repeat tile.

It should look like this:

Try your script again to see the pen trail.

Pick up your bot (right click) and put it in another place.  Run your script again.
 

If you get too many pen trails on the work area, look in the Pen Use category pane and click on the exclamation mark beside the Clear All Pen Trails tile.

 

Help - My Viewer Panes have Disappeared!

Sometimes they are just tucked away and you can see a small icon like this on the right hand side of your window.  Click it and your viewer will pop back out.  

If they have totally disappeared, just ALT click on your sketch again and open another viewer.

When adding some tiles to scripts, you need to take care which part of the tile you pick up.  If, for example, we want to add the Bot's heading into a script, you must grab the tiles by the assignment arrow.

If you just grab it on the label Bot's heading, then you get a Watcher.  It will look like this when you drag it out.  A watcher just sits in the window enabling you to see what value something has.  It won't go into a script.

 

 
Try the following script and click the exclamation mark to run it once:  (Don't forget to drag the tiles out by the arrows where they have one.)
1. Write a script to draw a triangle, pentagon, hexagon and octagon.

2. Write a script to draw a pyramid like this:

3. Write a script to draw your own intials.
