This pattern I first saw on a motor cycle. Sheldon Brown also notified me of this pattern. Having 36 spokes all the same length (3X) it was easy to build, however all spokes are laced at some point (some three times).

Maintenance with such lacing may require the removal of other spokes to replace the broken one.

I think this is the best looking wheel I have seen,

A 32 spoke version can be built using 2 leading and 2 Trailing spokes (2X Length).

View below showing both sides of wheel
If you look at the outside spokes (At the hub) They are interlaced with all three spokes in the opposing set, The middle spoke is interlaced with two spokes, and the inside spoke is interlaced with only one.

The outside spoke are mildly curved as they run from the hub to the rim in the region of the interlacing
The valve is at 6 O'clock. As you can see there are only 3 places the valve can really go.

Try to ignore the shadows on the wall.
