Subject: Break apart a string by kind of characters

Hi all, I've an interesting problem. Imagine the following string:

'a1000aa'

I want to break it apart like so:

[ 'a', '1000', 'aa' ]

I did a search on the forums and came up with this regex:

'a1000aa'.scan(/((.)\2*)/).map { |i| i[0] }

Which is pretty close, but it groups on a change of character, so I
would get:

[ 'a', '1', '000', 'aa' ]

I tried playing around with the regex (e.g. swapping the . for (\d|\w))
but to no avail.

Any ideas?
