I tend to keep my tabs open for a long time in Firefox. You see, I collect stuff over the days and weeks and don't really do much with them except just keep them hanging around.
My latest obsession is with Lego. I have a medium sized box of them on my desk but no real time to play with them these days. I've taken my obsession online and found a couple of neat things related to Legos.
The brickfactory has a nice collection of Lego instruction book scans. I'd really like to help this guy out by offering a free mirror of his stuff in the US (in fact, I just sent the email over to him to see if he'd be interested).
Fibblesnork has some free
lego backgrounds for your website (or desktop even).
If you are photoshop-aware, you may also like this nice collection of
lego photoshop brushes (and you'd also most likely enjoy this
awesome collection of photoshop brushes too).
You may also like this collection of
Lego Mecha Builders. There's some great work over there. I'm torn as to whether I should rebuild my Lego into their original intended sets or go bonkers and build awesome things like these here.
And of course there is always the
darker side of Lego.
And finally, there is the
Lego Digital Designer that can help you plan out projects like the Lego Mecha or whatever else your Lego heart may desire.
Of course, if you are ever at a loss, you should check out LUGNET, the International Lego Users Group.
