I did a modify to this hack, and now it works ALSO with "forumid", which lets you choose if displaying the last 10 posts from ALL board, or from a single forum
if you call it with ticker.php it gives full forum
if you call it with ticker.php?forumid=PUT_FORUM_ID_NUMBER_HERE then it will show latest posts only from that forum....
Check it out
DISCLAIMER: use it at your own risk ( but it works

)
NOTE: change the colours, board name, etc... in the code, to suit your needs
