Aaron Tiensivu has created a nice installer for XsX‘s alpha-blended cursors. Not only do they look cool, but Aaron lists some very good reasons for using them:

#1 The cursors change color based on the action performed (Normal/Link Select/Etc)
#2 They are easy on the eyes, professional looking, and most importantly, easy to locate on a laptop LCD.
#3 They work well on Citrix and Terminal Server sessions with low color depth.

You’ll have to pick your .inf file after you’ve installed these, so be sure to read Aaron’s posting carefully to make sure you use the right one. Aaron’s thoughtfully included a mouse scheme that uses these cursors, too. Custom alpha blended (semi-transparent) mouse cursors – Link
