These examples were exported from ACSLogo as SVGs, and are shown here without change. To view them you will need Firefox, Opera, or the SVG viewer from Adobe. If you click on View in own window next to each picture, you can view the picture in a separate window which can be resized to scale the picture as required.

You can zoom in on the pictures by holding down the command key (the cursor should change into a magnifying glass) and clicking on the picture. To zoom out, use the shift key as well. See how there are no 'jaggies' as you zoom in. Magnification works best if you view the SVGs in their own window.
