mouse cursor

Hi gang,

This is so far off-topic I am not even sure it belongs in THIS forum! I have been banging my head against the wall on this for days, and since this place is full of the smartest people I know on the Internet, I thought I'd post here to see if someone could allay my increasingly painful headache.

How, under OSX 10.6.x can I either change the mouse cursor image (say to a single transparent pixel), or just disappear it completely?

We are demoing a UI for a specific piece of hardware (which isn't ready yet), but need to show it on a computer. Problem is, the specific piece of hardware will not have a "cursor" and showing a cursor will detract from the demo.

I have looked at Apple Script, and it seems like there might be a way there, but I cannot find it. I have looked at cursor replacement/enhancement add-ons but the all modify the existing arrow, rather than remove or change it completely. And I have tried the simple things like hitting an arrow key, which works, but the moment a mouse event is fired it appears again, and our entire model hijacks the mouse events to handle navigation on the screen.

ANY input would be TREMENDOUSLY appreciated!

Cheers,

Chris
