Pfft. Herding cats is easy. I do it twice a day, every day.
The grass thing, however…WAY cool! 
Cool. Now, if you can figure out how to make a time lapse movie of paint drying just as interesting, I shall be yours to command forever.
If you type in “Time Lapse” at YouTube you’ll get other things like this (only without the cute ending).
Another thing to do is to look up “High Speed” on YouTube, for the flipside.
Great video.
One week and a hand full of bird seed huh, cool.
Great ending.
BTW, here’s a commercial of cowboys herding cats: http://www.youtube.com/watch?v=Pk7yqlTMvp8
When you speed up a clip of a dead mouse, play Phillip Glass if you want to be decomposing 
That’s great, wonderful use of technology, science, and humor.
I am actually planning exactly this. (well, the bit about the paint, anyway)
Heh, heh - great again.
