How To: Fold a linked triangle-sided modular origami ball

This linked modular origami ball, composed of many touching triangles, reminds us of building those large bridges and skyscrapers with our plastic link toys as a kid. This modular origami ball works on the same premise, only it's made of paper.

Before you embark on folding this cool empty-centered origami modular ball, be warned: This is not for the butterfingers or beginner origami students among us. With a multitude of sides and a delicate balance of paper that keeps the ball from collapsing in on itself, this is one origami project that should be attempted carefully.
