Screen capture, again

I know there are alot of screen capture programs out there (camtasia, captivate, snagit, wink - for those of you who don’t) but what i want to achieve is something along these lines.

My guess is that this was captured using wacom tablet or other.
Is this possible to do with these programs? Because I wouldn’t want the whole screen to be captured. Anyone got an idea on how to make such a movie?

after some testing out with array, i came out with this :

but still confused with object vs array…
