Most of us has one, how long have you been working on your pet project?
Mine is bbTracker. I've been working on it since July 2007. As you can see I've been neglecting it quite a bit ...
My pet project is a math library I wrote to replace my Computer Graphics' teacher's ad-hoc implementations of everything whenever she needed it. I've been working in this since July.
I wrote it as a series of C++ headers, but now that I'm on vacations (and therefore don't have anything to do), I will put all those classes in a DLL.
Mine is FastFlex, though nearly dead now for over an year, worked full-time on it for some time.
Myne is a way to grab streaming stock quotes from Yahoo and put them in a database. I've only been working on it for a week so it isn't nearly finished.
I have so many pet projects I can't even count :) I think this is also my problem - I always find some more interesting issue/problem that I have to solve :P
Only project that has gone live to this date is J2ME handsets database

Twitterlicious: http://www.ejecutive.co.uk/projects/twitterlicious, which I wrote when there were very few Twitter clients around, but now there seems to be a new one every week.
Mine is whatever code I hate working with and want to improve. Keep working on this kind of pet project and eventually management makes it a real project.
Umbraco Interaction Layer which bridges the gaps in the Umbraco document API. It also provides a LINQ interface to Umbraco.
I have countless little pet projects, and many more on my to-do list. however I quickly get bored with one and go onto another - so in reality I just have many unfinished utilities!
Mine is Project Hamster - the gnome time tracker. Have been working on it for 1.5 years now!

I'm re-writing it at the moment....
I've got several of them but only 2 of them are still alive. It's 3 years for one of them and 2 years for one of them.
I have don't want to be NSFW here ... but my pet project is sort of a web spider. Wich you can call an "automatic pr00n movie downloader". Been working on it, on and of, for about a year.
This actually started as an exercise in making a c# desktop app commuincate with the web via HttpWebRequest.
