I always liked programming, so here are some attempts at programming fractal trees. I started them after watching a video on Fractals with my son who afterwards started seeing fractal landscapes in his Bionicle movies. These images are in reverse order as I "improve" the original code. The code was written in PostScript and improved over time.

Here is an animated GIF image which put together the concepts from the previous trees (below).

Here are the four seasons. Clockwise: Winter, Spring, Summer, Autumn. I used a seed for the random number generator to get the same tree branch layout each time (with extra random calls where needed depending on the season). Different seeds produce slightly different trees. Here are the trees for each of four seasons.

I created it with a small PostScript program in a few minutes.

Here is the tree after a request to add leaves. The leaves are non-fractal for now.

On request, here is the autumn tree.

Here is the same tree before I added the randomness to the angles and branch lengths.

Possible future improvements:

• Have the autumn leaves fall at random to the position below
• Alter the angle and/or length of each leaf/blossom randomly
• Add icicles hanging from the Winter tree.
