eöööööööööööö — The Vuvuzela is definitely the unofficial symbol for the soccer tournament with teams from all over the world, which takes place in South Africa right now. (Am I allowed to say the original name, which is a trademark? I remember many people got sued the last time)
Whatever. I designed a Vuvuzela icon for the PICOL library which again is publish under a Creative Commons license.
David Carswell contributed a Microsoft Visio 2007 stencil incorporating the PICOL SVG iconset (090316). This stencil is an import of the SVG icons, with aspect-ratio protection applied, and is released under the same license as PICOL itself.
You can download the Visio 2007 stencil HERE
I coulnd´t check the file, beacause I have no Visio. If there are any problem please contact David
PowerPoint and OpenOffice support eps files, but changing the color of the icons isn´t possible with eps files. If you export your icon as *.emf (Enhanced Metafile) you are able to change the colors with PowerPoint, but you lose all your curves, if you look closely on your icon.
It took me some trials to convert the icons made with Illustrator to make them editable with PowerPoint. It takes a few steps, but it works. Now it´s possible to change the color of the icons with PowerPoint and OpenOffice.
