As I’ve said before, I like the look of iChat. So when I made the switch yesterday to Adium, so I could use both the AIM and Google Talk (viz: Jabber) protocols at the same time, I began a hunt to have Adium replicate the look of iChat. If you feel similarly, I’ll save you some time.
First, don’t download the official Adium client. Instead, download Metal Adium X by Mike Barca. That will give you the metal look for the chat window(s) and the Contacts list, as well as Aqua-y goodness for progress bars, etc. As he explains on the Metal Adium site, Mike updates the app within 24-48 hours of a new release of the official Adium client.
Second, download iChadiumMod, so your message view will have the iChat-style balloons. Next, be sure to change your sound set to “iChat” in the Events preferences. Finally, you’ll need a new Dock icon. There are a few iChat replica icons on Adium Xtras, but I didn’t want an exact duplicate. I’d like to be able to tell my apps apart, thank you, so I went with the iChat Adium derivative.
Looking at my chat setup now, I can’t help but wonder if this is near to what iChat would look like with tabs:

I’m sure Steve would have the tabs at the top, a la Safari, but otherwise, pretty darn close, no?
Dude, iChat supports jabber, so if thats the only reason you're using adium, you may as well switch back.

Zach,
I'm aware iChat supports Jabber now, but I'm addicted to having a single chat window, with tabs for each person I'm chatting with (see screenshot above). iChat does not support that, and it's the sole feature that's keeping me with Adium.
