Here is a PDF of the Vector file I uploaded yesterday called Thristico. It’s like an infinity loop, useful for those diagrams that clients like to produce that shows things working together, like “information > feedback > improvement” that kind of thing. To be crystal clear, this is not a licence for you to use this file anywhere you like, this file has previously been sold on iStockphoto as a royalty free file and as such if you were to use this as part of a logo for your client you would be unable to trademark that logo. If however you wanted to use this file in a project, something like part of an infographic for example, then go ahead, you have my permission for that. Just don’t come asking me for sole use or a licence to use in a logo etc, because I’m unable to grant such a thing. I will however sell you the original illustrator vector file if you wanted to make some adjustments which are hard to do from importing the PDF file I’ve supplied.
