Update (11/19/06): NOW INCLUDES 3 CURSOR SCHEMES... Medium (Normal), Large and Extra Large (XL).
Get the new Windows Vista Cursors from Build 5744 RC2 on your Windows XP machine. There are just a few aesthetic differences. The new cursors are antialiased and have a crisp look to them. The hourglass cursor is replaced with the loading indicator (as seen in Internet Explorer 7).
