I really like how her hack doesn't involve using another video feed, which makes it a lot more accessible to anyone with a laptop.

One improvement I can see - maybe better to tape the pencil with the eraser point up, so you're less likely to accidentally stab yourself with the pencil if moving the laptop or CD?

We could drastically cut costs with a nickel instead of a quarter.

2 pennies would be cheaper. Here are US coin weights, in grams:

  5.670 quarter
  2.268 dime
  5.000 nickel
  2.500 penny

The pencil's orientation might be deliberate as the eraser provides additional stability due to its friction with the back of the laptop.

I have the same thought when I see the pencil tip is pointing upward instead of the other end.

Probably try to lower it down enough to fit one CD.
