Are there any must have programs for these computers that make use of the fun new hardware they have?

I found MacSaber last night, and its really fun:

I have also heard about SmackBook, but haven't tried it yet.

Likewise, are there any programs that use the built-in camera, like a facial recognition security program? I'm loving my new MacBook and want to test its capabilities!

Delicious Library's barcode scanner via iSight is pretty sweet.

I was adviced last week in macnn to use Journler as a diary application.

Pretty much I run all my activities, blog and web writing, emails (importantly) on it. Integration with iWeb is great. Integration with iLife is perfect. Allows to record audio and video and keep it with wherever project you are doing

It is a killer application for scientists, writers, bloggers, and many more.\

Best way to keep progress of your everyday work while saving ideas, dates, and future work in order.

It is free, although I'll soon will sent a book to the author. What a high quality piece of software.
