I have to say that, as a proof of concept, it is an interesting thing to see. Yet, I find no need/use for it, nor I think it looks good on a weblog. If the "movable" boxes would attach (stick) to certain parts, on an organize way, would make more sense. Otherwise, just some cool thing that I can' t code. IMHO.
There is a problem with acronym, when the word is between parentesis i.e., (AOL) or between --, like --AOL--, perhaps even "AOL" (haven't tested that one) it will not work.
