Necklace for a guy?

[sxe-afi-freak.livejournal.com]

Alright, gals (and guys?).

I present to you, a question.

A friend of mine's birthday is on the 18th, and he's having a party. Trouble is, I don't know what to get him.
[More specifically, I don't know how to go about making it for a 'him', rather than a 'her'.]

A while ago, I mentioned I had made myself a necklace, and he said he wanted one.

The question part: Any idea what I could make out of black and white sead beads (he loves black and white, and I have tons of sead beads right now)? I don't have a whole lot of experience with jewellery making, so if it isn't too difficult, that would be awesome.

I have no idea how to go about making a necklace for a guy. I don't want to make it too 'girly' or anything.

Help?!
