Ok, so the CSS transform rotate, used to rotate the tiles, DOES WORKS on IE, BBUUTT IE has a a custom meta tag to allow websites to tell it to act like a retarded. (That is: to emulate an old version.)
And guess what... the forum had this little snarky line:
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />
telling IE the Earth stopped to spin in 2009.
It should be fine now.
