"The time reversing ladder"
So it's a ladder to an attic and as you climb you go back in time slowly but surely.
As you climb there is a light on the next floor that seems to get further away, but always it is one floor ahead.
People on the ladder do not seem to be directly effected by the time reversal.
People on the ladder can dismount at any time to look around the attic, and can even take and place objects, although this has been suggested against for obvious reasons.
Would like to hear if anyone thinks it's a good idea, bad idea or anything else for that matter.
Don't want to waste time sandboxing it if it's not a workable idea.
