The 1.0.4 version of Spirographer X for Mac was provided as a free download on our website. This Mac application was originally produced by Naoya Tozuka. The software belongs to Design & Photo Tools.
From the developer:
Spirographer X is a virtual spirograph drawing tool. Therefore, with this illustration tool, you can draw virtual spirograph star-like shapes. You find a small gear and a ruler which has a hole where the gear rolls about. All you need to do is put the point of the pencil in the hole on the gear and roll it.
