They are a very cool company, and their products are really top notch. I purchased their screen engager personal 20 picture application a while back. Obviously, the need to send them new pictures and pay them some more to create the revised ScreenEngager was a pain in the neck. Their newer BBViewer and ScreenEngager Dynamic seem to be much better deals -- though I must admit that while going through all this I came across an open source application on the Java developer site (posted by Klaus Thiele) that allowed me to do this myself for free. If you have a technical bent to your personality, I highly recomend trying to learn how to do it yourself
Now obviously none of this applies to the Traffic Cam applications :D
