Always keep this list updated, we will need it when the guest character start to appear ^_^
Anyway... For the first comic I was thinking that the programmer guy could be on his computer doing his thing and after a while he screams something like "I did it!" (we don't need to explain now the mathematical implications of what he did) and look at his own computer with happiness. After that a message appear on his computer saying "I saw what you did. You have 30 seconds. Run." he gets confused and a group of swat-like soldiers storm his house.
