I found a new freeware utility that lets you change the boring cursor icons that M$ provides you with. It's probably one of the best freeware i've ever tried and even the freeware version gives you plenty of themes and options to choose from.
Personally, I hate using freeware that's bloated, buggy or has limited options but this one is pretty darn cool. I tried another cursor icon package last month, but this one rocks compared to it.
EDIT: While you're there, you might wanna download other cursor themes created by other users (not included in the installation package). There's more software on that site to maximize your 'gooey' experience, but they are not free.
