What you see is a result of the drag & drop APIs allowing the drag 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.
