World’s First 3D Mathcast.

I just got a new 3D webcam called, “Minoru 3D Webcam“.  I decided to make my first 3D video a mathcast of course.  It’s silly and really just a demo to see how the 3D effects look.

I think my students will do a better job with this camera.  Stay tuned for future math video lessons in 3D.
