I tried looking in to this, and the best I could find was to make a sound file that was actually just a broken softlink (I think that was the situation), and when you told the system to play it, it would blink the screen instead.

i just read about this thanks to your post... i didn't even know about this "feature" (or whatever) for mac os x... it's interesting... my custom Mail.app sound never goes off for some reason when i receive new mail, i could use this instead... and also i hope this works for my method... i guess i'll have to get the fileManager to write a "sounds" folder in the library if one doesn't exist and write some file (apparently we can set a text file as a sound in the sounds folder to make the screen flash)...
[EDIT] oh, apparently it doesn't work with mail.app... oh well, no big deal... hopefully Snow Leopard will sort out the mail.app bugs with custom sound notifications.
[EDIT] aaaaand none of this seems to work at all in 10.5... back to square one...
