Clicking on the “Open” button above the image will send the numbers used to generate the Cyclocycloid pattern to a new window. In this new window you can change the colours, change the length of vectors, number of overlays, etc and export images and/or save the file.
 
(Each new window will use a substantial amount of computer resources such a memory. It is best not to open to many at once as this can slow your system down considerably.)
