My goodness, the robot is cool, but how did they get all those moving blue
lights in the background?!

I wouldn't be so sure, especially after reading Darren post. PITA for 
sure and the kind of work no sane person would do, but I wouldn't say 
impossible.

I might check at work some day, if I'll remember and if I'll have time.

Really? Care to explain that one?

Off the top of my head:

=product(range)^(1/count(range))

...unless there is some geometric mean function, I didn't search for one.

=geomean(range) which does exactly the same as your function.

Ah. In other words, "you don't need to code this because it's already 
pre-defined".

Or, to put it another way, I picked a bad example. ;-)

Or, a lot of what you might want to do in a spreadsheet is pre-defined :-)

Or, I use a spreadsheet in a way that's very different to how normal 
people use them.

(E.g., Excel doesn't provide a "convolution" function. And it would be 
far too hard to implement one in VBA. Not because the algorithm is hard, 
but because I'd have to figure out how to access the cells of the 
spreadsheet...)

I tend to use Excel as a function plotter - and it's annoying that 
things like an FFT are so hard to do.

The built-in FFT in Excel doesn't work?
In any case, accessing cells with VBA is basic. Just start recording a macro 
and put something in a cell to see how it's done.
