Warm Fuzzies in OpenOffice.org Calc

Once a mathematician, always a mathematician. I've been one since the age of 8, so when I came across FuzzyMath, a fuzzy logic add-in for OpenOffice.org Calc, I was naturally intrigued:

InrecoLAN FuzzyMath allows to use uncertain or approximate values in OpenOffice.org Calc. It means with InrecoLAN FuzzyMath you can perform ordinary arithmetic operations and use ordinary mathematical and financial functions with uncertain values as if they are standard, or crisp, numbers.

What's interesting about this - aside from the fact that it is maths - is that it shows that OpenOffice.org is gradually becoming a platform for all sorts of novel add-ins.
