One of our bigger clients, well actually they are our biggest client, wanted a kiosk setup with their sharepoint site on top and a scrolling ticker in the bottom showing CNN and stock news. So I went about researching various tickers that use java and javascript. None of them could pull RSS feeds so I had to write code using VBscript for that part. None of them would work with the length of strings that I was feeding them either.
I found one site that had the nerve to sell their tickers for... get this... $130(or something ridiculous like that) a month + $500 initial installation fee! Are they out of their minds?! All that money for a freakin ticker?! Well luckily I knew about IE's marquee HTML tag and ended up using that instead. The page is basically a frame with 90% sharepoint and 10% ticker in the bottom. It looks pretty good and even displays little images. The ticker is updated using Windows scheduler that runs a batch file that runs my script that reads the RSS xml from CNN and some other stock market site.
