Ok so I seem to find a lot of stuff around the internet that lets you ponify your computer so I'm making this thread Ill list any old/new things I find here. feel free to add if you find something too.

Pony Mouse Cursors Created by Coyoterrainbow from deviant art. Change your mouse cursor to your favorite pony

Pony Shortcut Icon this is a free program that changes pictures into .ico files so your pony folder doesn't look like a bland yellow folder no download required. (you can change all your shortcut Icons to whatever you want) Before and After Image

Pony Boot up Screen this only works for windows 7 that I know of. you will need Windows 7 Boot Updater and a Boot Logo Capt-Nemo from Deviant Art has a few premades however you can mess around with it and make your own too. Normal Windows Boot up and then My Boot Up

Pinkie Pie

You can change the boot screen in older versions of Windows too (I had a friend whose said Windows XPirated with a pirate flag instead of the windows flag), but it requires some registry-fu and does bad things if you mess up.

Ok, don't laugh but I'm still running XP, so I'm not sure if I feel like digging into the registry to swap out my boot up screen. Very tempting though to have my Pinkie bounce instead. Hrmm, might have to do it anyhow.
