Mathemusician Vi Hart is channelling the ooky spooky in this Halloween video that demonstrates Sierpinski triangles.
Okay, so we may have a little YouTube crush on Vi Hart, who uses music, student supplies and YouTube to demonstrate mathematical concepts.
Today, she's branching out a bit — using popular US Halloween treat candy corn and a prop skull to build a Sierpinski triangle.
If you haven't already subscribed to her YouTube channel, we heartily recommend it.
