No, that is part of CSS3 and it is not yet implemented by any browser.

Yes, at least I've done it using CSS float+clear ... but it doesn't work in IE (but I can't guarantee that can't be fixed, as I don't care) and you have to get the width and height standard and correct for all of the elements otherwise it looks bad ... the row below the one with the larger item will start just after the larger item instead of at the start. See my pictures archive for the code:

I've been meaning to blog about it, as noone else seems to be doing it and if someone would fix the above two problems for me that'd be nice too :).
