This is the Nouveau (onyx & iron) theme. It is available in two flavors onyx and iron (duh?) and each is available in 2 different sizes large and larger ( each is 64 X 64 but, the size of the main pointer is shrunk in the smaller one)
This is my second cursor theme so you can be a little less gentle with me.
Check out my other theme called Glasstic
I hope you Like it!
