I'm working on this financial
model<http://leeds-faculty.colorado.edu/moyes/html/documents/FinancialProjectionsModelv6.8.9.xls>for
my upcoming ecommerce business using OpenOffice.org Calc (and the
BASIC
programming language). But as the need for more advanced programming arises
(making the various spreadsheets more dynamic and interconnected, applying
algorithms for analyzing data and forecasts etc.) I can't help but think
that maybe this would all be a lot easier if it was Ruby.

Is anyone aware of similar financial models made using Ruby, and if so how
are they implemented? Are they simply Ruby wrappers for Calc or Excel, or
maybe Xero, or a dedicated Rails app?
