is there a way to change the cursor? I made a cursor trail with the script i found here but i would like to change the cursor too.

Are you talking about the actually cursor? Or a cursor trail?
Theres a lot of cursors here : Soup Faerie.com (http://www.soupfaerie.com)
There mainly for girls though.. :-/
If you dont like any there, than search google.

look on the css section on here theres a few default cursers like crosshair etc...
