The Pinhole Effect



David Craig, an excellent teacher with the DoDDS System in Germany wrote to tell me, "Pat, your “Tiny Circles” blog got me motivated to finally make this Sketchpad simulation that I’ve had in my head for awhile. "
The blog was about the way an image viewed through a pinhole becomes more clear (although less bright)
David included a link to a Geometers Sketchpad demo that he made to illustrate both of these effects to his students, and gave me permission to share. If you have the GSP software, you can download the demo here.
Thanks for sharing David.
