Just putting out my attempt to create a minimal SVG image for the CERN logo:
SVG (WordPress.com doesn’t support uploading SVG as an image format):

Did you:
- ask WordPress to support SVG ?
- ask CERN to make this their official logo ?
I think it looks pretty good. Was it hard?
Not very; I checked against the highest resolution logo available at the time, trying to reduce it to as few parts as possible. The hardest part was realizing that the font was stretched horizontally. For a more difficult SVG project, have a look at the LHC Installation Circular Dashboard
