Marquee #2
This script scrolls a message from right to left
and left to right, using the substr function to cut the message
smaller and smaller and string addition to make the message larger
and larger. Watch the messages bounce back and forth.
Discussion
Like previous scripts, this JavaScript sets an initial
timeout in the BODY that is renewed in a function call.
Since the rightward scroll is slower than the leftward
scroll, the string increases in size by two going right
and decreases in size by one going left.
