Point well taken, although from what he was referring to (dragging
stuff in the finder) it's still likely that's the drag & drop api at
work.
I guess there's no cocoa support for those large cursors yet? I have
just checked the NSCursor docs and it states the image must be 16x16...
Thanks for the information anyway.

What you see is a result of the drag & drop APIs allowing the drag of
an image that represents the data being dragged. That image, can, of
course, be bigger than 16*16 (I guess the Apple UI guidelines also
suggest a maximum size for it).
I don't agree with this statement. I think that the cursor Olivier
referred to is inded a large cursor, as supported by Mac OS X via
Carbon / QuickDraw. This is at least how I interpret the following
snippet from tn 1176:
"Large cursor support has been added. It is now possible for
developers to build cursors larger than the 16-by-16 pixel cursor of
the past. In addition, it is possible to create animated color cursors
that are updated at interrupt level. The new cursor facilities allow
for hardware acceleration, which allows cursors to be rendered inside
of the screen buffer and for switching between hardware and software
rendering. To take advantage of this new facility, developers must
create a cursor plug-in component."
I'm not 100% sure that this technote is applicable for Mac OS X, but I
couldn't find a disclaimer stating the opposite.
My CursorZoom preference panel use a QD function to *scale* the cursor
to a larger size, but I think it's possible to also create a new
cursor with a larger bitmap. I haven't tried it out though.
