I find it very intresting for those people who build guitars!

There are tons of woods with different figures, some amazing figures.
For example Snake wood! thats just awsome

Check that webpage, I spent a lot of time having fun looking at thos pics and imagining cool guitar tops

Edit: Now they sell fingerboard blanks

I think some snooker players have their cues made out of it. Among other things, I haven't looked but it is supposedly very expensive.
