Here are some banner's I developed for the Spread Open Media movement. I couldn't upload the svg for some reason, but here are the pngs. There are several different ideas here. I like the "Get SOM" slogan. It's catchy and can have several meanings...but is intended to tell people to support open media file types. I'd appreciate any comments

This is clipart converted and broken apart that has been released into the public domain because the document says so, and its from NASA, a USA government agency. The publication is called "The Brain in Space:"
