What other mods do you use?

I'm just asking all you lovely people on the forums: What other mods do you use?

Let's see how diverse this gets! We're on the ComputerCraft forums, so it's a safe bet we all know what our favorite is, but what about the other ones you can't live without?

I MUST have Redpower. I am pretty good with vanilla redstone, but it's so hard to hide, and even a simple function, a T-Flip-Flop, press a pressure plate and it stays on once you get off, is MASSIVE in vanilla. In Redpower? A block. Singular. Toggle Latch. Redpower is fantastic.

Also, as an odd one I use, can I recommend Clay Soldiers? It's a fun little toy, build your miniature armies and have them fight to the death.

I also like Equivalent Exchange. (Guilty! Get the lynch mob and 7 feet of rope!)

BuildCraft, IndustrialCraft2, PortalGun :D/>/> ,ClaySoldiers,LittleBlocks
SPC, Zan'Minimap, Unofficial Better Enchanting

RP2, More Explosives , NEI, InvTweaks, Macro mod(used to do some simple tasks) and Optifine.
Some fun mods to use with CC.

RP2 for the cabling and logic,
IC2 and BC for all the machines you can build,
Equalavent exchange also for some machines,
Railcraft and Steve's carts for epic huge rollercoasters,
optifine, just because
and the Laser mod for huge color screens.

Rei's Minimap
Optifine/MCPatcher (for HD textures)
