Ok, so we all should know that TVTropes is just a huge shopping mall for writers to pick ingredients for their stories. You still need to chop them, mix and cook in a good order, stirring, but there are few things not catalogued there (hackerspace movement being one of them). Here's a list of tropes useful / inspiring for this story:

• Cast Calculus
• Characters - Characters and Casting
• Switching P.O.V.
• Ensembles
• Elaborate Underground Base - actually that's a pretty good name for a hackerspace
• Four-Philosophy Ensemble
• Teeth-Clenched Teamwork
• Limited Social Circle
• Loads And Loads of Characters
• Garage Band
• Family Of Choice
• Quirky Household
• Cast Herd
• Caper Crew
• Breakfast Club
• Band Of Brothers
