ImageMagick and Ambigram software idea. Ambigram Magazine charges for theirs. So they would not be suited for the opensource community.
Have ya heard of this new trend? If you watched the movie angels and demons you have. Well anyway getting back to the idea.
Use ImageMagick and an opensource script font and Caligraphic font. To create the Ambigram Software. Outsource the job on GURU.com to a php programmer according to your budget. Post back with your progress. So that I can use the software thanks.
Check out this link for a great Ambigram Tutorial and buy a book through the amazon links on the site.
