A collection of circles (and ovals), inspired by the circles I saw in p2pnut's composites tool ... several of these circles I found ready-made in other  fonts (I apologise,I didn't note down the designer's name so I can't give credits --- I'll try to backtrack though as I don't blindly copy things and hand out as my own work. Most of these circles I made with the bricks available in the fontstructor, for some I made the composites, some I assembled using shapes and composites made by others.

Thank you to everybody who enabled cloneability of their fonts so that I could see in detail how you made those tricky/exciting curves (to either recreate them and the composites under my own steam or to import into this tool kit).

This is a work in progress as I discover more curves made by members; with the new FontStructor we all will have more circular excitement coming...
