Good Client-Side mods for Minecraft?

I have been looking for some useless… But cool client-side/cosmetic minecraft mods… Some types of mods I like are:

-animation mods

-sound mods

-followers mod (kinda like wisps or pets)

-animal mods

Once again, I'm only interested in client side mods… Which means you can go on a server and they will still work. If any of you guys have come across ANY type of client-side mod you like, I'd be happy to know the name of it.

1.7.X

Added (1). please no lighting mods, I already know about them.

Animal and follower mods are impossible as they usually involve adding new content to the game's files which removes their client-side suitability. Unless you get a custom texture pack which replaces the standard meshes to meshes you like, but it would be weird since (for example), your "wisp" pet may be clucking.

For animation mods, you can look into Better Animations mod: http://www.minecraftforum.net/...on-revived.

For sound mods, you can look into Matmos r26 Environmental Ambience: http://www.minecraftforum.net/...atmosphere.

I recommend Optifine for maximum effect.

Alright, thanks.
