I've googled a lot without any success so far. I'm aware this could be created via Photoshop or some other graphic design software, but I'm trying to find out if there is some sort of tool that, for example, takes a base image and renders one like the logos on the above links.
I'm betting I'm gonna have to create my own "by hand" with graphic design software, but I want to exhaust the options first.
Any help will be greatly appreciated! Thanks!
