I'm sometimes asked for more explanation of the process in creating these. Okay. We start with a grid and take turns drawing a strip which must intersect with an existing strip. It's like Words With Friends only with comic panels. Here's a GIF that demonstrates the order in which we created this latest comic. The strips I wrote & drew are in blue. Martin's work is in green. We spent less than 2 hours making this. (Not counting my later digital inking, since we draw in pencil.)
