I have recreated the logo for the Starship Heart Of Gold as it appears in the background of a few shots in one episode of the 1981 BBC TV series version of Douglas Adams's The Hitchhiker's Guide To The Galaxy
I have created it completely in Inkscape. One episode of the show that it appears in is Episode 2, where our heroes are on the ship itself. The logo appears on the back of a Heart Of Gold sales pamphlet that Ford Prefect is holding. The logo also appears in Episode 3, on the front of Eddie, the ship-board computer.
I have uploaded the images that I screengrabbed from the show to create my final logo. If you want to see it in action, the show is pretty easy to find online. I think it's even on YouTube.

Since I created it in Inkscape, it's a vector image. The XML that you can save as a .svg file and open in inkscape is available here: http://pastebin.com/raw/zh7NYVeD
