Animation Question - Duplicate Objects

I have 30 duplicate objects - I need all 30 of them to change their animation state every 1 second...

Basically, these objects have 2 animations - "off" and "on".
The scene starts out with all objects displaying the "off" animation.
Over the next 30 seconds, I want them to switch to the "on" state - one at a time... So ever second that goes by, one object switches from "off" to "on".

Now, I know I can manually toggle these on/off one at a time with events - but I would like them to be randomly selected.
So, each time the program runs, the objects turn on in a different order than the last time..

Any thoughts?

pick an object at random would be good to use here. see the attached, should be fairly self explanatory.

Awesome Dave, thank you so much!
I'll give it a shot when I get home this afternoon.
