Wow. I dunno how you managed it, but in Opera 12.16 you get THIS: http://i.imgur.com/mGRDWdp.jpg http://i.imgur.com/mGRDWdp.jpg I have never seen this before.

Wow. I dunno how you managed it, but in Opera 12.16 you get THIS: http://i.imgur.com/mGRDWdp.jpg http://i.imgur.com/mGRDWdp.jpg I have never seen this before. At 100% zoom it seems fine, this screenshot is at 150% zoom and after scrolling a few lines. I'm aware that this is probably a browser bug just as much as to blame your CSS. But I have never seen a webpage do this with just CSS! Somehow it doesn't seem to clear the screen buffer anymore, when I clicked the link on HN (not into a new tab) it even shone through the HN frontpage on the background. The previous page. What did you do?? :) (also that sounds like a cross-domain content leak waiting to happen, but that's Opera's problem). It's very contemporary glitch art, with the juxtaposed perspective demo screenshots shining through in the back, beautiful, but not very hack-free ;-)
