an image from the US government EPA "Sunwise" program. I converted it from PDF format, and removed all the "sunwise" logos. the source link is here - http://www.epa.gov/sunwise/doc/mission_story.pdf
Budokan Karate-do Logo, now in SVG!
Although not originally by me, I recreated the logo into an SVG format.
I did that for my club's T-shirt design, & I like scalable graphics.
