Solar Eclipse

While hiking in the woods yesterday, I spontaneously decided to build an improvised pinhole camera to see the solar eclipse. Materials used: a roll of toilet paper, some aluminum foil I found in a trash can, a notepad from my backpack, and of course, my trusted Swiss army knife. Here is the resulting contraption and the image it produced:
