Here is Lee Stranahan's entry, it's pretty good.
And I like this one even more.
NOTE: I removed the embedded videos and put links instead. The videos played automatically and simultaneously and were getting annoying...but click through and check them out. Also, I added Stranahan's blog to the roll.
I had started this post last Tuesday, and didn't realize how short the time to vote was...finalists will be announced tomorrow (4/29), I'd expect to see both of these among them.
