So, I recreated the Fleur-de-pensée in SVG format. Now you can download the image and scale it, or edit it to your heart's delight. And as I said before:
I'm releasing this symbol to the public domain, free for anyone to use, with only one restriction.I created 3 different Fleur-de-pensée image files that you can download: Inkscape SVG format, plain SVG format, or Adobe Acrobat format. The two SVG formats contain the Fleur-de-pensée inside of a ring – which can be removed using a graphics editor if needed. The Adobe Acrobat PDF format has two images, the Fleur-de-pensée within a ring, and by itself. Scale the PDF document and then cut and past it as you please.
The only requirement that I make is what this symbol represents. As long as anyone uses a symbol that is recognizably based upon or derived from the Fleur-de-pensée, it will always represent scientific, skeptical and rational inquiry into our natural world, without the need to resort to the supernatural. It also indicates a willingness to explore ethical questions that originate with humans and benefit all humanity while respecting individual human rights.
It would be neat if this image gains acceptance among Non-believers, and truthfully I hope it does. However I'm realistic, and I know what the track record for Atheist symbols is like. If you like this symbol, then give it a chance – link to it, download it, use it. Even play with it.
