Organizers are looking for original designs that are useful to multiple users but, in terms of creativity, they say the sky's the limit. Submissions can range from budgeting spreadsheets and personal finance templates to funky graphics and presentation templates, but must run on one of the suite's four main applications: Writer, Calc, Draw, or Impress."

clever but highly unmotivated trick.
