[edit] Revisions
- I've removed the title, and used an image caption instead - Egil 07:03 May 5, 2003 (UTC)
- I rendered it in PPM at a much larger scale, then blurred it and scaled it down in GIMP, and saved it in PNG format. Only the part of the source starting with "# Axes" was used. --MarkSweep 05:27, 15 Jan 2005 (UTC)
