This is a lot of fun. I created a variable called leaf, which I start at a value of 80. It sets the draw size of the leaves. Smaller values create bigger leaves and larger ones create very tiny ones so that the drawing looks more like a fern or a evergreen.

Great drawing speed from SPL.

Any screenshots are welcome!

Leaf size of 400.

Maybe for such trees the branches width also should be made thinner...

Yes, with a few sliders and switches this could generate endless fun.

[Mr. Kibernetik]

Yes, sliders and switches will be added as interface objects.
