This step-by-step powerpoint will lead your students through the process of creating a checkered optical illusion (Op Art) piece using a simple formula I put together. The last slide of the powerpoint is a student worksheet to figure out their design. Print it out at the beginning of the lesson. Take a look at the movie below to see how these might turn out.
The steps are illustrated in slides 6-8. Other solutions for the same steps are provided afterwards.

I love the pictures, but since I am a novice myself, I was looking for something that would help me give explicit directions. For instance, does it matter how far apart the lines are? Does it matter how many lines I put on the page? My students (and I) need step-by-step written directions to go along with the presentation.

I like the designn, but you quickly go from the circles and lines to a fully done piece, and I have no idea how to do the in-between step. Your guidance would be greatly appreciated.

On the Op Art piece, I know you just filled in every other shape but I don't know how to do that in PPT. Are you literally creating a new shape to fill in? Is there a way of grouping the shapes that you've drawn to allow for individual shading?
I draw in photoshop elements and export images into powerpoint. Then use the powerpoint as a guide for students to create a painting from. Students aren't making this digitally. They are painting. Does that clear things up?
