It demonstrates a neat effect. I'm sure many people like me soon were right-clicking to inspect the code.
edit:
And I'm sure this was done with just our kind of people in mind:
/*
Dear Source-Code-Reader
First of all, thank you for caring. Not that many
people view source. One of the beautiful things
about JavaScript is that it's necessarily Open-Source.
I like that a lot. I hope you find this source code
somewhat useful, and not too dirty. Remeber to
pay it forward.
Well, the source simply being viewable for JavaScript is not the same as all JS being released under an open source license! I guess this is kind of like an open source license, though.
