Kiosk App to Move Back on Top

[Sivakatirswami]

My little Kiosk app (Mac OSX) is coming along nicely.. at one point we 
invoke Safari to let the users sign up for web newsletters... Safari 
comes to the front.

Can I have a "send in 10 minutes" that will bring Revolution back up as 
the front most application?

If so, how exactly do we do that?  Infact I want to actually close 
Safari's Top window (so that the next user comes into Safari with a 
default page)   I suppose that will require a touch of applescript.
(of which I know virtually zero)
