Simple and effective
This is a very nice insight into the world of flies and their rather varied sense of humour they must posess when they hang around faeces all day. Love the fact that you considered it to be impossible for one fly to carry the pen, so you added a few more, as if it would make a difference :P Little details like that make all the comic difference :)
Are the flies regulars to your strip, or just a seasonal addition, while they appear to have joined a health club in the second one - you've given them access to the sauna, which has made me re-iterate that I will never use that particular facility in my own gym.
Just a quick idea for your project of videoing the production - have you considered using a program like Flash to record the action on the screen, to save you messing around setting up the video camera?
