Finally a way to get rid of that last pixel you see when 'hiding' the cursor in the corner during a presentation: put the cursor on the other screen. Much easier than throwing away a full line of pixels through adjusting the screen (if possible, think fixed beamer setups). But what if you show the audience 2 video signals and you can't control 3, so no private screen to hide the cursor on? :-) Or someone bumps the table the mouse is on during a movie and you're nowhere near the computer to get the cursor out of the middle of the screen? But seriously, you're post reminded me of something: http://lists.w3.org/Archives/Public/www-svg/2002Nov/0024.html

Norm -- the S5 presentation system from Eric Meyer does some really nice Javascript magic for presentations.

Funny to see such great minds discover today tricks I've been working with for ages. Used to work in the late 90's in a little web design company, where I learnt that trick from a semi-illiterate graphist. He worked with up to three extra screens, the main one for the code editor, one for, say, IE rendering and the other for Netscape rendering, and an extra one for unameit application running. Since then I feel miserable when I have only one screen to work with, and have always the second one available at home. And in demos, it's really cool indeed, keeping the public screen clean and all the gory things on your private one.
