I prefer this centrifuge set because it is complete and you made a left version.
Centrifuge 2.0 Lefty Cursors
a custom cursor set that I wanted to make and upload for sharing and safekeeping. if you want to use it as well, feel free. This theme in particular is made for left-handed users.
new 2.5 cursors available! legacy cursors will get their own set if you prefer them.
