I find myself drawn to flowcharts whether I understand them or not. Here's why.
From Wired, here's a flowchart that guides you through making a single-serving site, using single-serving sites. If you can follow all this and actually make one, I'd like to hear about it.
This flowchart by Mortal Wombat details George Lucas'Â thought process in 1997. It won an image competition at Cracked called 20 Insane Supervillain Schemes In Flowchart Form. There are 19 more villainous flowcharts posted there.
In another Cracked image competition, this one on celebrity lives in flowchart form, Derelictman presented this flowchart representing Salvador Dali. This is one of the few SFW finalists.
The crazier the flow, the funnier the chart will be, as in the Driving Test Flowchart. This is just a the beginning of the flowchart; the actual chart is three times as long!
Holy Taco has a flowchart to answer the question: Are you going to have sex on this date? (link may contain NSFW ads) Keep in mind this is written from a male point of view.
Also from Holy Taco, check out the flowchart on whether or not you should get a divorce. More useful, depending on your life situation, is this flowchart from Twisted DNA about finding ways to have sex after you become a parent.
