DHTML for sreensaving?

[jimminni]

Dear all, I'm looking for DHTML for a screensaving function please.
I've looked through all of my HTML & web development books and can't find anything of the sort.

Jimminni,

Javascript would be very limited as a screen saver.

Native Javascript can only affect the contents of window(s) under its control but not their chrome. It can only close subordinate windows (ie windows opened by itself). It has no general authority over other applications or the screen as a whole.

There's may be some ActiveX control but it would not be universally available to all users/browsers (as is indeed the case for Javascript itself).

& added to airshow's reply
taking over the hardware, for any purpose, is a typical act of malware.
Browser makers release innumerable updates to separate the browser from contact with the underlying hardware
If you did find such an exploit, browser makers would be quick to close it in case some person with 'less than ideal' intent were to use it for other purposes

Valuable words from Bob - as always.
