Novelty Blinker!

I created this script as a novelty alternative to the erratic and hard to read "sideways" scrolling text displays prevelant today. This one blinks one or more messages. It's only purpose is to show that just about anything, even a "blinker", looks better than "sideways" scrollers.

Blinker! is compatible with most JavaScript capable browsers, including Opera , HotJava , WebTV , Netscape Navigator and Internet Explorer.
