Perl is indeed wonderful, partially because of how silly the programs can end up looking (there's a module that'll turn any program you want into the shape of buffy the vampire slayer whilst removing pretty much all the alphabetical characters, and it will still run. That's how silly it gets). Other than programming stuff, I don't know - learning a new language? (Admittedly difficult if you have to learn from a book). Musical instrument? (Likewise, plus I bet your neighbours will love you if you practice it at odd hours). Writing fiction? You've got a talent for writing - we wouldn't be here otherwise - try doing something slightly longer form? If you want more challenges in your work, how about when you first turn up you make the situation even more ridiculous and see if that helps. (OK, now I've got to get the trapped woman with the broken leg out from under her bed before the snakes get her whilst avoiding stepping on any cracks in the floorboards, and all before 'Song 2' finishes). Maybe it'll even fulfil a quota.
