I made some Christmas ornaments in Desmos that I hope you will enjoy. If you click on and off the circles on the left of the descriptions, you can see all eight ornaments in one Desmos graph, or you can find them all pictured below in this post. If you click the arrow next to each description in Desmos, you can also see the equations used to produce each ornament. However, the snowflake and Rudolf’s face required many ordered pairs, which I put into a separate folder.

1. Decorated half red and half green:

2. Decorated with diagonal stripes:

3. Decorated with sines and secants:

4. Decorated with a snowflake:

5. Decorated with a checkerboard design: (This was a pleasant surprise that required only one equation!)

6. Decorated with a spiral

7. Decorated with ellipses for a 3D look:

8. Decorated with Rudolf’s face:

Perhaps you will choose to make an ornament yourself in Desmos. If so, I’d love to see it.

I hope you all have a very merry Christmas!
