Sock suggestions?

[jackandahat]

I've turned out a few pairs of plain socks using this as a guide. Now I'd like to do something more interesting.

The thing is - I'm probably going to have to alter it some, because I have strange feet (long and skinny). A lot of patterns I've seen involve something around 60 stitches cast on in 4ply on 2.75. My current socks are 48, and they slouch, it's just if I made them any tighter they wouldn't go over my heel.

So I'm looking for something:
+ Interesting enough to not just be A Plain Sock
+ Simple enough that it won't break my brain (I don't know what my skill level is, but I'm not that clever)
+ Can be altered if necessary.

Does anyone have any suggestions? I'm hunting through Ravelry, but of course personal suggestions are better.
