@Setanta,
You want to do this with paper and pen or with a cadd program? If it's a cadd program, maybe RP can help.
First, though, read Mankoff's blog/notes at the New Yorker - he's the guy who picks the cartoons.
Second, eat a lot of oranges, they'll fix you write up, right up, and then you'll be able to include asians in your scenarios.
Next, interview djjd, that man has an eye for what's going on. Oh, and Gargamel, same comment. Together they could make bonfires of a lot of vanities.
Don't oscillate, the ocelots will get agita' and then Roberta the Cheetah will have to rescue you.
What the hell is a Venutian?
