Lewis backdates his Minecraft to 1.7.3 and looks at a combination of awesome industry-style mods compiled by an awesome fellow named Kakermix as the "Technic pack". I have shied away from this for a while because it's so complicated, but once I got stuck in, I realised it was totally and utterly awesome.

End Splashscreen by Lalna:

The Technic combination mod pack is out-of-date and completely unofficial, so use it at your own risk! You should be able to find a way to downgrade your version of minecraft back to 1.7.3 with this mod:
The Technic pack is available to download here: v2:

Version 3.1 is also out now complete with an installer! Just make sure you've got a clean version of Minecraft 1.7.3!
v3:
Also a torrent for 3.1 here:
