Is there a tweak on Cydia that will allow you to do this on your dock:

This pic is from '07, I know, but I do remember seeing something similar on YouTube a few weeks ago.
I don't think the icons have been skewed or anything, I have a funny feeling that they will straighten when the dock is slid across.
I thought Infinidock would do this, turns out it doesn't. ='(
