Played around with a Koch Curve Creator (makes 3 types)
Can rotate and resize it.
Drag the X label points to resize. Popup save to png.

ENJOY some snowflakes.

Would like to know how to save frames to animated gif programmatically
while rotating and making bigger from a smaller size.  Kinda like
zooming in on an animated rotating object effect.
Saw something in another thread but kinda stuck with the process.

Hi,

Amazing program

Try this (using BGRABitmaps)

I change some name and parts of the original program... Sorry.

Wow, Dzandaa, thanks for the nice solution. Fantastic.

I see you used the BGRABmp to do the animating.
The file size of the gif is very small.

With the 1 sided Koch it seems that the curve is moved up
automatically (even if one moves and resizes to a new position
initially), but the other two Koch curve types work beautifully.

Much appreciated.
