Lifestep, heh.

This is not THAT grand of a decision to be making! :O

Litestep's a little more user-driven as opposed to user-used. You get out of it what you put in.

You don't have to "program" anything, but it'll be a lot more satisfying if you do customize it a bit.

Windowblinds is what you want, as Immortal said ;)
