These are more trademark than copyright questions. If someone wanted to create brand confusion they could free-hand the dodecahedron on the left, use a (marginally) different font for the lettering, and it would not violate copyright at all (as long as they only used the ideas from the original logo, not any actual copying). > I know, that's probably controversial and discussing this only > consumes time that's better used for something else.

Just like > donated money can't be used for buying beer. I think this just makes things messier--what if I want to make a shirt that has the Sage logo on it? Do I have to get permission from the Sage project? Do I have to get permission to put the logo on my site with a link to Sage? Can I change the colors to better fit with my site's theme? What if I think it can be improved by adding texture to the background, or (as started this email) tweaking the lettering? Are these derivative works even allowed? If so, are they also explicitly dedicated to the Sage project? If I produce, say, a project that allows one to use Sage on an iPhone (or, even, uses Sage as a backend for my iPhone calculus application) can I incorporate part or all of the logo into my application's logo? A concrete license like the CC makes things so much cleaner, and I think CC by-sa is an excellent fit. - Robert --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
