In My Sierpinski triangle project that can be viewed at (http://scratch.mit.edu/projects/3116188/#player) I used Barnsley's Collage Theorem to compute the Sierpinksi triangle. The Collage theorem plots individual points that accumulate along lines. In this project, a moving point creates a single line that traces a series of increasingly smaller nested triangles. Even though it looks like Sierpinski's triangle at higher levels, I am not sure it is Sierpinski's triangle so I simple call it Nested Triangles.
