This is the freshly laced front wheel. I love the curvy spoke pattern. It's only curvy because the spokes haven't been tightened yet. After they're tightened, they'll straighten out and look more normal.
Bicycle wheels are amazing things. I've actually built a few wheels before. It's considered relatively advanced. I find it amazing to take all these little parts, none of which has any rigid strength. And then you put them together to make an amazingly function and strong wheel. If you like wheels, check out this book. The Bicycle Wheel, by Jobst Brandt. It’s a classic, for those into this kind of thing. Sheldon Brown also has a nice article explaining how to build a wheel.
