15-word Logo contest

Download Logo for Free!

If you don't already have a version of Logo on your computer, we hope you'll download one. It is fun to enter the one-line codes from the 15-word contest and watch each picture get created. Often you can get a very different effect just by changing one number. But the one-line codes just give you a small taste of what is possible with Logo. Download one or more versions and start exploring! (If you need help getting started, go to the math cats' mailroom and send us a question.)
