If it ends up in base 36 then it's still going to get numbers in it, just
not for the first ten numbers! :)

To the original poster.. no, it looks like you're doing it the best way
IMHO. What you are trying to do is not standard (that is, base 26 is
0-9a-p), so a single 'tr' is nothng to sniff at to get your special variant
:) Just abstract it away into your own method on Fixnum/Numeric if you want
to keep it lean in your other code.
