1. For Netscape 2.x, Netscape 3.0x and
Microsoft Internet Explorer
No special feature of JavaScript supported only by Netscape3.0x is used.
All the browsers above can read this LED sign.
2. For Netscape3.0x
New functions of JavaScript is used. Only Netscape3.0x can read this LED
sign. But no error would occur even if read by other browsers.
An alternative text string is shown when other browsers are used.
3. For Netscape4.0
Layer tag is used in this LEDSign. This one works faster than the two above,
but it takes a while for it to initialize.
4. ActiveX LEDSign is also available.
This is the fastest and the smoothest LEDSign, although it is not written
in a script language.
5. Java Neon Sign is a Neon Sign applet that
can be seen by many Java-supporting browsers.
