Of the options that have been discussed, which one are you most interested in?
Asterisk (one central panel leading to several completely different linear storylines)
Wheel (one central panel leading to several linear storylines that connect in a neverending circle at the end)
Center-Outward (central panel progresses in two directions simultaneously; results in one linear story)
Outward-Inward (first and last panels kick things off and meet in the middle; one linear story)
Choose Your Own Adventure (exactly like Comic Whispers 4; no description hopefully necessary)
Magic Square (sort of CYOA-ish; see maga_dogg's page for more information)
If you don't like any of those ideas and want to see something else entirely, what are you interested in?
Which, if any, of these exciting Comic Whispers variant methods are you interested in? (Check all that apply, obviously.)
Caption Competition (you fill in the previous panel's text)
Invisible Mimesis (there's some sort of gentle connecting theme through all the panels; warning, may result in coherence)
Finally, and perhaps most importantly, how many panels are you willing to draw?
