Risugami's Mods
Risugami has some very cool mods. I(360pakman) made a mod pack out of some of his mods. The most important mod is modloader cause you need it to work any other mod you want to install.
Toomanyitems
If you need a block but you are not in creative you can use this mod to spawn it in. Also you can change your gamemode from survival to creative.
