Hi,

I run a small opensource software project (among other things) called Gryphon. It does something pretty technical and difficult to explain, but it is a little tradition in my company that we create a mascot for each of our projects, of the animal shooting lasers out of its eyes. We have a current mascot but it is not very good and we came across your alternative Gryphon images. We were wondering if we could use a version of one of them as the base for our mascot. If you email me I will send you the image we want to use. I fully understand if you are hesitant, I know that you make a living from this, but you will be fully credited and we are not making money form sharing this project. Please let me know either way, you can check out the project at https://github.com/BusinessOptics/gryphon .

Cheers,

James.
