Log scales = animation scales?

[David Bovill]

Great - that will do the trick Scott!

I think it would be good to separate the number series generated from the
action - so that you could animate various properties not just the loc, and
also it may have a very minor speed benefit at the cost of slower start.
>From a couple of tests you can't fluidly animate more than a very small
number of objects at the same time. So generating a lista and passing that
recursively deleting an item each pass may help a little.

NB - how does RunRev compare performance wise in animating simple controls
compared to Flash - I know Flash has a lot of nice features and s set up for
this - but if you just want to animate a button across the screen, or as i
my case a few pieces of text in fields (changeing there size)... is Flash
any faster?
