Automatically moving pushable blocks and crushing party.

[DrKojak]

Is it possible to make an automatically moving pushable block?, and if a pushable block moves onto the space occupied by the party is it possible to crush/kill the party?
I want to make a 3 tile wide corridor with a few of these moving block traps, having the pushable block going 2 spaces east, then 2 spaces west without any pause or with a half second pause between each space.
It so far seems impossible, has anyone any ideas how this could be done?

Thankyou!
