Large Custom Cursor

[bhip]

Hello everyone,
I am building my second website. I've chosen HTML because it's what I've worked with before, and I think my demands will be simple enough for it. Probably the hardest things I'll do with it are embed video and trying to create a large custom mouse cursor that is about 300 x 400 pixels, and is active on the entire page.

How would one create a large cursor? I've gone through hoops of creating a .cur file with a PSD plugin, but dimensions are limited to a small size. I also found a javascript tutorial at this page:

and have tried to recreate it a few times but it never works for me.
Thanks!

Changing the cursur image via css has not worked for me ever. This should do it:

body {
	cursor: url('my-mouse-pointer.cur');
}

It doesn't, but if you use the pre coded images like:

body {
  cursor: crosshair;
}

It does work. Maybe someone has an explanation or a work around?
