T-Square (fractal) - Definition and Overview

The T-Square is a fractal curve of infinite length inside finite area.

T-Square, evolution i six steps.

It can be generated from using this algorithm:

1. Image 1:
   1. Start with a square.
   2. Subtract a square half the original length and width (one-quarter the area) from the center.
2. Image 2:
   1. Start with the previous image.
   2. Scale down a copy to one-half the original length and width.
   3. The previous image's square has four equal quadrants. From each of the quadrants, subtract the copy of the image.
3. Images 3-6:
   1. Repeat step 2.

The method of creation is rather similar to the ones used to create a von Koch curve or a Sierpinski triangle.
