This cursor theme has been made by J.Aroche, it has been converted by me to a X11 Cursor. Also included are 4 different versions, blue, green, red, yellow. The 'busy' animation has been changed on all four versions, since the original is too big and doesn't integrate well with compiz-fusion enabled.
