I'd like to know this too and also how to install a new one. There's no more "manage boot animation" in the new ROM Toolbox and I can't flash a zip through CWM (it just freezes on installation).
Oh, I found it. It's under the Quick Commands menu (thunder bolt icon) and Manage Boot Animation, where you can disable it at least. Kasey, those options you're referring to are for the old Liberty Toolbox. There doesn't seem to be an Install Boot Animation option in this ROM Toolbox.
Liberty Toolbox->Liberty Tweaks->Manage Boot Animation->Disable Boot Animation(faster boot) deletes the boot animation, and Install bootanimation.zip on SD installs a boot animation from your SD card (Note: you have to have a file named bootanimation.zip on the root of your SD for this to work.)
