I rely on Chromium to aid in my web development, and have done so for the past couple of years. Inspect element has a firebug built in effect which is hard to beat, although I haven't done much with the console. Even though I've poked around with this for a while now, I picked up some great tricks from Paul's video. If you do any web development you'll enjoy it.
Thanks to Paul Kinlan for the heads up
ps: I caught the video in my tweet stream at the end of February and reshared it, but only tuned in to watch it this morning thanks to knowabout.it's video feature. Log in to their site, then select videos on the collection to see all the videos in your social stream.
