Open Access logo - help

Trivial as this may seem, I'm trying to find out who designed this "Open Access" logo, and whether there are some original files for it. I've seen this logo (or variations on it) on the PLoS web site, the open access publisher Hindawi Publishing, and the Mac OS X program Papers uses it.

It's driving me nuts that I can't find the original.

It's sometimes desirable to have different formats of an icon, and ideally have a vector-based version (e.g., in EPS or SVG) format that can be used to create images at different resolutions, and these projects provide these files.
