Java-Powered Tube Animation
This page shows a little experiment in Java programming.
When you first reach this page, the
rectangles at the top will be blank at first, while the Java
applet downloads the images it needs. The images may also blink
on and off for a little while until everything is present
Eventually, you should see five miniature GE tubes whose
innards glow and fade rhythmically. Real radio tubes don't
behave like that, of course, but it's a neat visual effect
and learning to program it taught me a little about Java.
The applet appears only if you're viewing this page with a Java-enabled
browser such as Internet Explorer 3.0
or Netscape 2.0.
If you're using some other browser, you may not see the images.
This Java program uses simple techniques described in an
You could achieve similar effects using animated .GIF files
