The first two animations made it into the show as part of the continous storyline. The others were stings that for various reasons didn't make into the show. The whole show played on the "Doctor Who" series, which is where the robots (darleks) come from. Also as a side note is that these are the raw animations with no postproduction, so it is not exactly as it appeared in the show.
I also found this animation, which I haven't posted on the blog yet.
