Learning Perl

I have had the intention to learn Perl for several years but have never really had a good project or a good book to start with but now I seem to have both! I just found the Picking Up Perl online book and read the first chapters and it seems to very quickly introduce the basic concepts of Perl. So now its just to get started with the project, to extract some intersting data from my ADSL Modem and plot that using MRTG.
