This one was pretty much the idea of SignpostMarv Martin. He had the basic idea, and made up all the sets, and ended up doing the photography (since my system really wasn't up to hi-res work at the time).
I came up with the camera angles (just try communicating those to someone on the other side of the world), and came up with the dialogue. Working alone, I could generally finish a comic panel in about ten minutes. Working with a single other person (however helpful), pushed that time out to more like 90 minutes each.
Usually, I end up doing all the work alone as a result.
This was the first multipart comic in the series, and you see real comic-style word-balloons here for the first time, as I finally figured out how to make them easily.
