Looks really good. What are you thinking, a plugin that takes a fuzzy frame and produces a super-res from it?
Looks like the download link is out of service at the moment Working now.
Will have a read of the documentation meantime, looks quite heavy though, there's no "load a fuzzy png, process and write a super image" function and there's no examples of how to assemble the supreme library functions to come produce something useful. Maybe in download?
It uses IPhython, so may be a non-runner for Gimp.
