I just watched a video "remix" of Mr. Rogers, called "Garden of your Mind." The footage and voice are from his shows but the voice is electronically treated into a musical pattern (similar to Symphony of Science remixes if you’ve seen those).
For the new PBS Digital Studios, this video falls under the show category "Icons Remixed." Also included in this show category are groundbreaking television chef, Julia Child, and new age positive thinking painter, Bob Ross.
There are many additional, more contemporary, show categories. I haven’t checked them out, but it’s all free, viewable-on-demand content.
