One of my favorite Saturday morning kidvid shows was Fireball XL-5, a black & white space opera done with puppets. It was created by Gerry Anderson, who was also responsible for Supercar and Thunderbirds.
It was cheaply made and the special effects were crude, but there was a lot of love for the genre in these shows. You can't really recreate anything like these shows -- they were of and for their time.
Here's a clip of the opening and closing credits. I still think the tune is pretty jazzy.
